You're right. The source of the problem is more important, and I won't be any help there.
I digitize with my ITTP. Note, they say it's not yet rated for that, but it works for me. That might be...

If it's not too late send it back. I get repeatability under half a thou on my tormach with the Hallmark ITTP and markings on the spindle and tool to ensure the same rotation and low speed probing...
kenrbass, you're a camaster guy now right? I don't think I can be sold on a helical rack and pinion being comparable to a proper ballscrew setup. Even if you can demonstrate the same backlash (which...
Shop Sabre doesn't offer any 5 axis options do they? Is there anyone out there who has taken a shop sabre and added this to their machine?
And assuming they don't offer it, are there any...
Do you know of any other CNC makers of large machines (4x8+ travel) that use two giant ballscrews on the longest axis? It does seem like a pretty good option to have them fixed and the nut rotating....
ShopSabre uses 12+ foot ballscrews on their IS 612 if I'm not mistaken. They rotate the ballnut rather than the screw to reduce some of the problems, but is this still a significant compromise? What...
From the picture it looks like you have vertical racks with plenty of chip debris collecting on them. That could be one source of inaccuracy.
If the two tracks that your gantry run on are not...
There's no question that for this simple part, a cam pattern can be used.
I must have either missed Jim's suggestion or didn't understand it at first, but that's what makes the most sense as a...
I know what my machine's accel values are, and if Fusion 360 did, it might actually be able to give me some accurate simulation times. With a lot of tight corners, I end up with 2x or more actual...
.2mm off on a 10mm hole is pretty bad. The last time I interpolated a hole that bad it turned out I forgot to tighten the nuts on my vice ><
Something is wrong, I agree. I'd double check your...
Jim is correct. Almost always, when the shaft of the tool is equal in size to the cutting diameter, the cutting diameter will be smaller than what is listed. You can try to measure them by hand to...
Knowing me I'd make a key and then never trust it, so I'd be indicating the edge of the vacuum table every time it came out. I should be able to do 95% of my work with the vacuum table in place. Only...
I think this sub forum must be where amazing projects go to get ignored. That thing is just incredible.
Patterning a 3D feature 40x20 times doesn't give me this issue.
Is a 40x20 pattern of a simple square really too much? I'm trying to model a vacuum table and my 40x20 pattern is absolutely destroying fusion 360. It runs great otherwise, but I turned down all the...
Spoilboard may not be the proper terminology. A custom vacuum fixture might be a better way to say it. I need to be able to re-use the same spoilboard/vacuum fixture many times, over many days, so...
Using image processing to do automatic edge detection with a microscope? I like it. I wonder if it would take you more time to program than the entirety of the time you'd save. Most likely, but that...
I don't have a spindle microscope yet, and that would require a tool change :)
I typically use smaller end mills, so it should not be hard to make my gauge tall enough so that I can contact off...
I'll be looking for +/- .001 precision or better. I'm thinking making a 3 axis touch off plate may be the way to go. I'll make it to work for stock corners or to fit in the grooves of my vacuum table...
I'm in the process of making a custom vacuum table that will have accurate stops for positioning stock and custom spoilboards. The spoilboards will be 1/4" polycarbonate because that's what I have...
Well when it comes to making CNC mistakes, the consequences of this one were cheap for me - there's no carbide on the floor! I just want to be sure I don't cost Tormach any potential customers. I'm...
I'M A MORON - This report was not accurate. PathPilot does NOT LOSE POSITION jogging to soft limits as I originally stated.
kstrauss was right. I must have had some inertial issues with my...
I'm not going to complain about this issue anymore. The workaround is easy enough:
-add force manual tool change in your code wherever you want to pause and do workholding mods
-separate into...
It's not a problem during a single program run.
The problem arises if you run a program, stop it, jog an axis to a soft limit while setting up workholding, etc, then start a new program that...
*****This is inaccurate. PP does not lose position when jogging to soft limits*********
1. They are not being disabled. Pathpilot uses a buffer too, I didn't measure the exact amount, but it's...
Well if I ever upgrade to galil controllers (which would only happen if I got servos) I'll let you know and offer my free testing services :)
Maybe you should market DawsonCNC :) Probably servo only at the moment though.
I hear ya. Obviously there are limits of what to expect out of the Tormach software team. They build PathPilot on top of LinuxCNC, not from scratch, and if this is the default behavior of LinuxCNC,...
There's a tightening screw and a locking screw. I forget which is which, but the tormach manual will tell you. Since you're already close to where they should be, I'd skip the dead reckoning step and...
