We have two HAAS VR-11's and we use Surfcam as our programming software. Surfcam puts out 5 axis code where some toolpaths have a G143. If I understand it correctly this function gives you the ability to not have to enter gauge lengths in the software. I for the life of me cannot figure out how to get this to quite work correctly. Currently I must edit the G143's to G43's and enter gauge lengths in the software. H offsets are set 1" off the table with a 1-2-3 block and are entered as a negative number. Then the Z origin is set with a shift in the work coordinate, example: If Z0 it 4" above table, then Z3.0 would be in G54. Then when 5 axis code is run, the gauge lengths are entered in the software, and the pivot length is entered in the post processor. Then the g/l's must be entered in the control as a negative number, I happen to enter them in the wear column, and the pivot length must also be entered as a negative number, I subtract it from the Z in G54. Does anyone know how to make G143's work?
Thanks, Mike.

Hello All,

I just made a move on a used 2007 HAAS TL-1 (no no enclosure, tool changer or coolant dispenser) - its a basic model that meets most of my needs since I am just getting started :-)

1. It didnt come with any schematics or electrical diagram to troubleshoot or understand the electrical apart from whats obvious, can someone share them if they have them please.

2. Since I have never used a HAAS controller, cane someone guide me to where I can find out whats options have been included with the machine such as rigid tapping, macros, etc.

3. How do I figure out whether it has a gearbox?

4. Anyone know whether I can rig a coolant dispenser that can be controlled via the controller, or even guide me to where I can find a pre-owned one for this machine?

5. It doesnt seem like the linear bearings have any wipers on them as they are exposed, looking to add way covers so also looking where I can get them.

6. The spindle motor upon start-up makes some frictional noise, but not when running - anything to be worried about?

I realize that I have a barrage of questions - its a very expensive proposition for my standards so making sure I an using this puppy correctly since its my first HAAS investment.

Thank you to you all HAAS guru's, hoping to learn from you all :-)

Shaffin.

Hello All,

I just had my newly acquired used 2007 HAAS TM1 machine hooked up and I was trying to jog it only to notice that the linear bearings were a bit dry for my liking. I opened the cover up and tried to apply grease through the grease nipples only to notice that the z-axis grease pipe feed is blocked!!!!!

Spent more than half a day trying various ways to pump but nothing works - it now seems tat I may have to replace the grease pipe run to the right z-axis linear bearings, and may have to replace the bearings :-(

Has anyone had any experience doing it or have guidance how to go about doing it? I dont have access to service manuals or anything if someone can share any information.

Thanks,
Shaffin.

Hello,

On my HAAS TM1, it states on the spindle cover that it support 40 taper with dimensions for CT, BT and DIN/ISO tooling - does this mean that I can use both CT and BT tooling with the specified pull studs????




Thanks,
Shaffin.

Hi guys,I need your help for installation TS27R OTS and Mounting OTS on a machine

I want to mount on TS27R OTS to milling Haas VF2SS,can someone help me with a procedure/instruction for installation,calibration? What I found in books by renishaw not helped very much.
And I would need to know where can be found variables stored after calibration ?

I want to know in which variables are stored values after calibration.
For example : #500 : X location
#502 : Y location
#503 : stylus dia
and what are the tolerances which not to be exceeded on each axis : exemple X 145.345 ± 20/0.020 microns
Y 124.344 ± 20/0.020 microns

working on a work instruction for OTS settings and all data offered by you dear colleagues,will be introduced in instruction.

Thank you very much dear people!

Does anyone have a program to warmup the machine before use? The manual states that the HAAS controller includes one but mine doesn't have it. Can someone share one I can use with my TM-1.

Thanks.

91' model VF-1

Loaded a part and in mid feed cycle x axis takes off in jittery rapid moves before my guy shuts her down.

Cycle power and we get this 103 alarm when trying to power up restart with the machine moving in X.

X axis cable is 6 months old.

Moved X cabling/ wires to Y axis card, still have X axis 103 alarm. X card deemed good.

Pulled caps off the brushed motor and cleaned all 4 ports of carbon. Still have X 103 alarm.

Not sure how to diagnose the encoder so if anyone could help there that would be great.

I did notice when I reset the alarm (machine now in handle mode) and grab the ballscrew and turn it to move the table away from the limit switch area (table moving right) the table will continue on it's own power to move right. This I found odd as it seems the motor is still trying to run without any control input.

Could it be the motor has a short? Possibly more carbon in the motor causing a short?

4 hrs in and i'm still scratching my head....:willy_nilly:

Haas Y axis over current alarm

My 1995 VF-0 (a hobby machine) has been occasionally throwing Y axis over current alarms ever since I got it. I've done all the recommended diagnostic steps, including cleaning brushes, checking cable resistance, checking for tightness in the ball screw and bearings, swapping drive cards, cleaning connections, checking supply voltage, all with no luck. I found marginal resistance values in both the cable and motor, and ordered a new motor and cable from Haas (ouch!) and installed them; still no improvement.

The alarm occurs every few minutes. There is no specific place in the Y axis travel that it occurs. It happens in any mode- during machine homing, while manually jogging, and under program control. It never happens when the machine is sitting still. It seems not to happen during continuous y axis movement- only at the start or stop of a move.

The machine will sometimes run for 10-20 minutes fine, then throw the alarm a few times in a couple of minutes. Yesterday I ran a long series of parts with about a 3 minute program duration. I ran the jobs for 12 hours straight. I got some sequences of 10 parts without an alarm, but would occasionally alarm twice on one part. The alarms occurred at different places in the program, but would sometimes occur twice in a row at the same move. The frequency of alarms did not change over the duration of the run.

I'm wondering if the acceleration at the beginning or end of the move is causing the alarm, as a result of something marginal in this old machine. I checked parameters and the X, Y and Z axes all have the same parameter settings as follows:

Parameter 21 Y Acceleration = 1500000 (note that the Haas service manual gives an example that has this parameter at 1200000)
Parameter 24 Y Fuse level = 25% (note that I found another thread here that said this parameter is usually set to 25-35%)


Does anyone know the implications of reducing the max acceleration parameter, or increasing the fuse level setting to 30 or 35%? Do the Max Acceleration parameters of all three axes need to match to allow accurate interpolation, or does the position control limit itself to the slowest accelerating axis?

Any other suggestions are highly welcome. This old machine is working great except for this problem.

05' VF2ss. It used to be once in a while, I would power up and be greeted by this:



It has been becoming increasingly frequent. And now it is every day. The only thing that has changed is the ambient temp here.
In the beginning, I would say, maybe once a week? And, it only happens during power-up. It has never happened once the machine is running.
It has always been a simple matter of red-button then green-button to clear it. And it would never happen on the second try.
This morning, it took three Red-button/green-button cycles to clear it. I killed the main between the 2nd and 3rd cycle just cause.

I have had a tech connect the main power both times I have needed it done. And he said everything looked spot on.

Anybody else had an issue like this? I am starting to worry :ill:

My gut says its the spindle drive. And its probably something stupid like a cold solder joint or something. You know something that could be fixed for free if you knew what it was. Rather than $5k for a drive! :bawling:

Has anyone got a remote jog handle on their older (pre 99) VF? The Haas distributor is checking to see if there is a factory kit, but I'm wondering if anyone has done a home brew solution. It would be pretty straight forward to wire up an MPG, but the axis select looks trickier.

A solution needs to be rock solid reliable or it could be a safety hazard.

Hello everyone, I have a 2005 Haas TL 3. I had some service done on the machine about 6 months ago. And the tech put it in what looked like GUI mode? I have the ips and vqc on the machine. I have software version L06.12n. Does anyone know how to get I into it. Thanks ahead of time for the info.

Guys, I have a problem.

Might be retarded and can't figure out something this simple but ...

How do you enable the Rigid Tap option?
I have the unlock code but I cannot enter the dammned thing!!!

About 6 months ago I had to reload the software in my MiniMill. It got corrupted during the battery change.

Anyhow, after the install ( actually a couple rev. worth of upgrade) all saved parameters and settings were properly reloaded.
Few weeks later, I got the 144 alarm. Had the code, entered it, all is well .... or so I thought.

Until now I did not need to tap, so I've never noticed that the Rigid Tap option also got disabled during the software load.

I have the 4 digit code
I turn off Parameter Lock
Get to the Rigid Tap option in Parameters
I type in the 4 digit code and hit ENTER

Nothing happens, the option remains at 0

What am I missing?
This is the code that came with the machine back in 2002, and it was working fine until the sw load.

Thanks

I have never really run a cnc mill or lathe. I am currently farming out alot of my production work. I want to buy a machine to do it in house, not to save money but to make sure the work gets done. I will be buying new and I will be paying someone to program the machine for me and I will be the monkey who pushes the button and opens the vice. I looked at the TM1 but have been told that a tool changer is a great thing to have and to be fully enclosed. I have sort of decided on a Mini mill I cant afford a vf1 and I probably couldnt keep it busy enough. I dont have any large parts but most parts are mild steel. I dont need to haul ass since I am currently doing it all manually on old machines. I want to buy a Haas because there is lots of service available right here in town. I have looked at other machines but the price is important I dont want to be flat ass broke paying for a machine. What kind of deal can I expect to get on a base model mini mill and what kind of tooling would I need.

My Haas SL-10 counts the tool use twice every time I run a cycle. The tool may be called up only one time in the cycle, but it still counts twice. Why?

Hi, got what probably is a simple question. I've got a VF-4 (2009 i think) and i'm trying to figure out how to change the tool type and flutes on the control. Must be pretty easy but i haven't found the screen. We never paid attention to that setting before but now that i'm doing a lot more one-off stuff having a easy viseable chipload reading on the screen is actually pretty handy.

So just to be clear if my tool 1 is a 2 flute center drill my screen thinks it's a 4 flute Endmill and is giving me the wrong chip load.

Thanks.

We have had reoccurring alarms 648 & 649 :dc bus under voltage, dc bus shorted. These alarms were only on initial power up each morning, and could be reset after 30 min. to 1 hr. until now. We cannot clear them at all now. Have been advised that it's almost certain to be the vector drive. Anyone run into this before?
Thanks

I keep on getting a question that pops up when I save a program to usb asking if I also want to save offsets. I'm sure it's a setting but can't find it. I don't want that option to pop up.

Tell you why. I teach CNC and have 16 Haas simulators and some students have been saving programs with offsets and I would like to eliminate that.

how many people have a Ha5C indexer on a VF-2?

I want one for our new VF-2 coming. I calculate I would have to make a subplate to shift it to the fronT of the table by approx 2.00"

Will this work and will the handle clear?

2009 VF-2. Just today I got the 147 Z limit switch alarm. Tried the typical shut down and restart. Worked for a little bit then shut down in the middle of my spindle warm-up. Looked on here and could only find y and x limit switch issues. Where the heck do you find the z axis limit switch to check if there are chips on it or if the cable is broken? Anything else I should be looking for?

Thanks,
