can i take x2 4th axis rotorys and make a 5th axis with it?
stupid i know, but i have one and there are a few 5c units for super cheap right now, it would be fun to dabble with some plastic projects i have, but i wont have any paying work, hence not looking into a expensive trunnion
(yes i have 4th and 5h drives/software unlocked on my machine)
is this possible/ easy as plugging both in and bolt up/align properly?

I have an SL20 and the C axis has stopped functioning. Is there parameter in my control panel that might have turned it off? All systems seem to be ok and the board has been tested and its ok. Last time it worked, a tech was working on bar feed parameters. Any ideas or leads would be greatly appreciated.

Recently had to pull the table off my machine for service work to the rails and trucks. In doing so I removed the OTS from the table to prevent damage. Machine is back together, all aligned, squared, and working properly in that regard. For reference, this is a 2011 VF3SSYT classic controller.
Reinstalled the OTS to the table today in the exact same position, and ran the calibration procedures as I normally have in the past using a precision ground calibration bar in the spindle(Maritool). After doing so I pulled up a tool that had been in the machine and previously calibrated prior to the OTS removal and ran the probing cycle as a test. The cycle ran as it should, however the OTS is calculating the tool diameter(or radius in this case)incorrectly. Tool measured out length wise within .0001" from previous measurement, but the radius was WAY off. The tool is a 1/4" diameter 4 flute endmill, and had a previous radius measurement of .1247" The OTS repeatedly records it now at .0327-.0328" instead. We're not talking a few tenths or even thousandths. I have run the calibration process a handful of times today and nothing changes. I pulled the batteries out and reinstalled them today in the OTS as well and did not touch the stylus during the startup procedure.
What else should I be looking at here? Could something have changed without my knowledge while the probe was off the table? I had the probe stored upright tucked into the corner of the cabinet behind the controller, so it wasn't getting bumped around in a box or drawer somewhere. I am not that familiar with the actual macro(s) itself, nor the parameter settings on the machine so is there a specific data set that I should be looking at to see if something changed? It just has me stumped as the way I see it if the OTS was damaged it wouldn't be reading the Z axis length correctly, but it is.
Anyway, any help would go a long way here because it's either that or calling a tech back here

So we've got new UMC-500 recently to use as a production machine. Machine itself is great, no problems holding tolerances, surfaces finishes are good.
But, this is not production machine that you will be running one shift let alone 2 shifts. The problem is that tons of chips end up in chip tray and that causes the coolant to drain slowly which in turn makes it overflow and flood the shop.
We have belt type chip conveyor and high pressure pump.
I hear other people have problems with this and I do not see it being talked about.
What do you guys recommend we do to address this, because as it is this machine is not usable? We can't have someone constantly clear up the chip tray.
This is chip build-up in tray after a single part we ran. If you don't clear it immediately next part will flood the shop:

Anyone else having problems with their newer Haas bar feeder that uses a timing belt? Mine worked till a little past the warranty period and has turned into one PIA since. The issue is the belt slips on the drive pulley. HFO has installed a new belt onto the feeder and has been having the same problem. The belt had a sideways curve to it, looks to me an issue with too much tension and too much torque for the system. It feeds fine for about the first 3 feet of a 4 foot bar and then it looses position by slipping the pulley. The step where is slips is in the pulling the pushrod back. This step the feeder moves at 100% rapid. Is there a way to slow this action down?
There are three permanent fixes to this problem system.
Firstly would be slow the rapid down on the pushrod return. Does not look like this is operator accessible.
Secondly using a bigger pulley on the servo drive motor. Of course this would require a parameter change to the control and I am still not sure that the current timing belt can stand up to the torque for long periods. Probably would still still require slowing of the rapids. Also thought of making the pulley longer, 2" wide instead of 1" and keeping the diameter. The changes that require Haas to change parameters are probably out.
Thirdly would be to replace timing belt with a chain drive. I am slowly thinking that this is the way to go for a bulletproof drive system. I am sure that Haas did not go with a chain is they would have to lubricate it and the timing belt requires none.
This bar feed system should be more robust than what I have encountered. I operate a job shop where we tune 1" dia to 3" in less than 1000 piece orders. Cant imagine using where it ran for long periods without operator intervention.
Any comments would be appreciative. Thanks

Hello,
I am looking at and would like to purchase a Haas TM-1p. The problem that I have is they list the machine's max height at 105". My shop/basement has an unfinished ceiling at 93" and 102" if I go up and between the joists.
Looking at the layout drawings, it looks like I could get the room I need by modifying the feet and framing out the joists for an area large enough for the Z axis and cabling.
Has anyone had the same problem and does anyone see a problem with modifying the feet? Also, I realize that would need to tilt the machine to feed it into its home and have the equipment to do so, but I am not sure about attachment points or any other issues with tilting the machine.
Thanks, Tom

So my friend noticed that he could tell his UMC500 that it has a SS rotary installed.
My friend is very happy that his C-axis spins a lot faster now.
Are there any physical differences between the 500 and 500ss rotaries? My friend noticed that they both have the same rated torque, which leads him to believe they are the same hardware.
Please let me know if my friend is an idiot.

Keep it under $50,000 dollars if you can. that's what I paid for the whole machine.

Ok so my Macro knowledge leaves a lot to be desired so hopefully this is a simple question to someone else.
I am trying to locate a skewed part with the Renishaw probe using
G0 G90
G65 P9023 A15. I8. J4. B1. S54.
Basically that touches two points along the x and y axis and records the angle in the parameters.
I8. is the x location of the second point and J4. is the y location of the second point.
The first point of each axis is 20mm
My problem is the part I am locating has a radius greater than 20mm so the probe is still touching radius
Is there a variable to edit this?
I emailed this same question to my Haas apps guy but figured I'd ask here while I was waiting
Thank You

I had a ball bar test done on my vf0e which is a year 2000 model,
The backlash in the machine is very good, Ive just fitted new x axis ballscrew assembly, all new bearings in x & y and cleaned out and checked lube flow and fitted new metering units on x & y which is all good
But you can see I have servo reversal spikes in x & y and the mismatch which is causing the majority of my errors
My question is what is the best way to get rid of these errors and why do they come about?
The machine as said is mechanically sound so it is not backlash as proven and it is not stiction due to bad lube system

Good morning
I am attempting to figure out how to use the wips on my new to me machine. It didnt come with any instruction manuals, and the ones I have found are only for the new control. Any one have a link or direction on where I can get a manual for the 2011? I see in MDI where probing is located but need further instruction.
Thank you

I just wanted to pass this information to possible save your machine from premature wear. We have a VF6 and a VF2 that just turned 2 years old. Almost two months ago I started getting a 2082 alarm.
(image below shows the grease plugs)
"2082 RESIDUAL PRESSURE DETECTED PRIOR TO AXIS LUBRICATION CYCLE"
The VF6 would hold 90psi all weekend long powered down. The machine also use the purple grease. Well I can tell you that the purple grease clogged every single line on the VF6. The clogging area is the fittings that the copper lines connect to. Inside of the brass fitting is a setscrew and the brass fitting it drilled oversized then tapped. The grease has to flow around the small void between the threads. It took a tech 2 days to remove the lines, remove the plugs and put it all back together.
We no longer use the purple grease, we use a synthetic oil from Kluber/Summit (Syngear SH-1150). Works great and I don't think we will have any problems after this.
From what I could find out it that the purple lub is a diluted with a thinner/spindle oil. I think what may be happening is that when the lub try's to go through void around the threads it is separating the oil from the grease and the grease is left behind. Over time the lub can not get through the grease clog. You can see all the "plugs" from the lines. They feel more like wax than grease or any lubricant.
Just an FYI to help save your machine!

Hello All,
I have been trying to figure out the mounting hole pattern on the carriage of a TL1. Seems it should be on the Haas site but I have not found it. Please share any information you may have.

Guys
My waycover slipped apart, and proceeded to properly sever the motor cables to my 4th axis.
The thinner, encoder cable is absolutely fine, only the power cable that's cut in half.
I will call tomorrow to find out, but does anyone know if there is a way to get only the power cable?
I see part numbers for the whole harness with the block that bolts onto the HRT210 rotary, but I'm thinking I won't need all that.
COULD try to just repair the cable itself, but if the replacement is only a few hundred $ then I won't bother.

Hi Guys,
I had a 2005 or 2006 vintage Haas GT-20 lathe land in my lap. One of my vendors wanted it off their floor and I got it for a song. This is the first Haas I have ever touched. I have Mazaks and have had various Fanuc type machines from various builders. So I am familiar with CNCs, just nothing HAAS specific.
Machine appears to be in good condition other than what probably caused them to get rid of it. It is giving a few alarms.
It gives a hydraulic alarm. I can hit reset a few times and it will clear. I can hear the pump running and pressure is showing on the gauge above the power pack and near the chuck pressure adjustment knob. Oil level is full.
It is giving a turret alarm. If I issue a M6Twhatever to change tools I see the turret pop out and then it gets the alarm. It doesn't rotate. Unfortunately I didn't take a picture of the alarm, but it was something turret related.
I also noticed that the hydraulic chuck is very very slow to actuate. On the order of about 10 seconds to clamp or unclamp.
While not doing anything, I do hear some variation in sound coming from the hydraulic pump.
I am thinking that there is something clogged in the hydraulic system. And that is causing the chuck to be slow. And perhaps is causing the turret to either not fully extend or not extend fast enough.
Is this a good hypothesis? Any suggestions on where I should start looking? Perhaps this is a common problem?
I also noticed that if I do a M19 P45; M14; it will orientate the spindle to 45 degrees. But it doesn't seem to clamp. At least when I open the door I can turn the spindle by hand. I am not even sure if it has a spindle brake or if this is more evidence of a hydraulic problem.
Thanks in advance for your suggestions!
-Jim

Hi,
Please see the hi-res photo here: objectivelyspoken.com/uploads/20210124_142711.jpg
This is a machine just delivered to my garage that I have yet to power up.
Before the machine was moved, the technician removed the Regen Resistor Box at the top of cabinet. This means he disconnected the regen cables. I have now connected the regen resister cable, and the regen overheat connector on P20 (above P15 on the left). According to the Mitsubishi spindle drive instructions the Regen Resister connects to P and PR so this seems where it should go.
Now I have noticed there are four 3-pin male connectors on the right side of the IOPCB that are bare:
They are P57, P58, P5(110), and P54(350).
There are also 5 female connectors hanging loose. (You can see them hanging on the right just in the shot.)
Er...did the technician remove these to get the Regen cable loose?
Must I plug them back in?
Does anyone have a shot of their cabinet they can email me showing what is plugged in and what is not.
This is a 1996 model. I don't yet have three phase power installed.
Thanks!
Paul
