A word of warning. Having tested lots of collets there is wide variation in hole parallelism and TTS contact area when the collet is gripping. TTS is dependent on full length gripping the 3/4 shank...

Different steels have different coefficient of expansions but assuming the height gauge is steel, stainless 410 is one of the lowest at 0.0000055 in/(in °F) and with temp varying between 50 and 75...
A couple points
There was a problem with too much oil pressure lifting the table or head when oiling during machining and making out of tolerance parts. This showed up more with the auto than the...
No. Here's specs for a new set
They are parallel within 0.0002", flat within 0.0002" and square within 0.0002".

What was the reason for using a block under the tool holder rather than putting the tool holder on an edge of the surface plate? I think any out of parallel between the top and bottom of the block...
Thank you.. As I understand it in another thread Kstrauss pointed out an obscure problem he was having that was fixed by an upgrade that was helped along by other users:
It's not just the super-duper new technology you're missing if you're not running the latest version. You can't help improve PP which would benefit all of us. For example if there is a problem or...
It's nice to see software supported by a company that solicits suggestions for improvements and features and makes updates available for free...
That could be the sound a stalled stepper makes. Try moving the block that activates the limit switch slightly closer to the center of the table.
Talk to Tormach. It could be a failed driver or motor and they may ask you to do a swap test.
I don't agree that is the only thing missing:
Cost of PathPilot software $110 (about)
Dollar cost of time to order, receive and assemble hardware and install software.
Possibility that something...
Try twisting and untwisting it with your fingers. You may be surprised how easily it winds and unwinds.
In looking at your motor coupling I was wondering if it could wind/unwiind as the load changed, causing positioning error?
There are bearings to take the thrust load but they are inside the motor. Conventional design has bearings on the ballscrew shaft and also inside the motor and I've always wondered about that. It...
Steve,
I think Tormach would be pleased. From their Our Story page: "Tormach is dedicated to helping people enter the world of CNC manufacturing".
Mission accomplished.
I have a different view of running a stepper motor into a hard stop. If the mechanics are robust enough, and the Tormach is, a hard stop will do no damage even after multiple stops. On some (all?)...
More generally it can be thought of as volumetric compensation . Use a laser to measure the error with regard to the location of the spindle in 3D space and map the errors in the controller. That's...
I think it's common for manufactures to specify both swing over bed and swing over carriage. Tormach advertises 6.2 inch diameter over the carriage so while you could face a 11-12" piece 6.2 looks...
What about two sided tape aka carpet tape?
Tormach has a kit with the moldable plastic. Hit it with a hot air gun to reshape.You'll need a sub plate to keep the part flat.

rx8pilot,
Tormach PCNC 1100 started with Series 1, then came out with Series 2 followed by 3, with earlier Series upgradeable to subsequent ones. Better control software (Mach 3 to Pathpilot), ...
I personally have not. I don't do that kind of work, I don't think I've ever tapped a 2-56 hole in anything, .I suggest you ask the person who owns one at the Tormach cnczone forum.or a manufacturer...
rx8pilot,
Welcome to the Tormach forum. I suspect you may find that the thread died because it is not a glaring feature omission. Off hand four tapping methods come to mind.
1) Tap mounted...
It is common for machines that do rigid tapping to use the same tension/compression holder as the Tormach https://www.mmsonline.com/articles/rigid-tapping--sometimes-you-need-a-little-float. You may...

There are never ending machining strategies. If speed and thread concentricity to the other features took a back seat to conserving material you could cut threads in the first op and then screw the...
How does approximately 200# (in-lb? ft-lb?) at the stepper relate to force at the cutter...?
I'm pleased Tormach doesn't have rigid tapping and hope they don't add complexity to the machine. I find my tension compression head works well and don't see much reason to have something else to...
This should answer your question starting at minute 2:25 https://youtu.be/0cM32grBMvo?t=147
I encourage review of the force, length and diameter assumptions as well as the calculations:
There are numerous web sites that have cantilever beam formulas such as at the top of DoITPoMS - TLP...
