Thanks. I guess I was assuming a lathe was the tool of choice, particularly since I don't have one :-) I might try it on the mill when I get time, and it can be almost any metal, so I can pick...

It's not my drawing, and clearly only a quick sketch. This is essentially an extension tube that adds 100mm to the existing tube. 9mm looks like the ID of the hole through the tube. That sounds...
I'm barely even hobby level when it comes to CNC machining, and I do have a PM25 mill that's converted to CNC. I still have trouble determining what the best way to make parts is, and as an example,...
Success!!!
Thanks to all who made suggestions, and especially those who had me question the controller. I first tried using the X motor and it's normal controller without having any of the...

I haven't tested anything yet today, but...
Thanks for the comments. I definitely agree that this is a mechanical issue, and someone who's passion is perfecting a milling machine might be able to make it work with the smallest steppers made....
A lower kernel freq is something I haven't tried, and it will be simple to test. This is an Ethernet interface that's supposed to be good for 400 kHz, so 100 kHz should be pretty conservative. The...
Thanks for the 23-34 adapter link. That was on my list of things to search for tomorrow.

Thanks for the comments. During my weeks of initially trying to make this work, I tried lots of different microstepping resolutions on the controllers, with the corresponding steps per unit. What I...
Acceleration is pretty low now, and even low single digit numbers didn't help as I recall. I'm not sure what you're referring to step pulse and direction pulse numbers. I don't see a setting like...
If I try to drive to the ends of the table, it will stall at any speed. I keep it at 50 ipm max, and it will stall way before getting to the end of the table travel. This is with no extra weight on...
Yes, thanks. I was aware of that. I might try measuring one when it's holding still. It's a pretty far fetched theory, but I'm out of better ones.
Rusty
Thanks for the comments. I spent a couple weeks fighting this issue, and I finally just set limits for X short enough that I could trust it. I'm certain the screw isn't binding, and no adjustment...
Greetings,
I'm still pretty new to milling machines, so keep that in mind. I purchased a PM25MV, and converted it to CNC using one of the common conversion kits. The kit uses NEMA 23 (570 oz-in)...
Thanks for the comments. The head spacer is probably the most common solution, but when you look at the movement of the saddle, it doesn't appear centered on the machined portion of the base. When...
This is exactly what I was searching for. I've been converting a PM, using one of the available kits, and I'm finding it hard to believe the Y axis isn't centered below the spindle. I thought maybe...
Thanks again for all the comments. I knew you could connect the computer to a windows network, but I didn't want to give the computer anything else to think about while it's trying to make parts. ...
Thanks for the comments. I do in fact run the g-code directly from the USB stick, since it saves the hassle of copying it. Of course that's not too much hassle if you never change your files, but...
I just edited the original post so it's (hopefully) clearer. I just want to be able to swap USB sticks without shutting down EMC2.
Thanks,
Rusty
Greetings,
I'm trying to learn to like EMC 2.4.3 (Linux 10.04), and I have something that is really confounding me. The machine (Probotix Comet) is running fine, and I'm using a USB stick to...
Thanks again for the comments. I ordered and installed the Platinum version, so now I just have to find time to learn how to use it.
Cheers,
Rusty
Thanks for the comments Harold. I took a quick look at the site you linked, but I'll spend more time there later.
Rusty
Thanks again Lee.
So anyone else using TurboCAD Pro or Platinum? I hate to think it will just be me and Lee :)
Cheers,
Rusty
Thanks for the comments Lee. It would be hard not to go all the way to Platinum if I do this. I just thought it was funny that no one seems to talk about the Pro or Platinum versions. Since I've...
There seems to be an extra $100 off for upgrades from Deluxe to Pro or Platinum until the end of the month. It's listed on the upgrade page:
Deluxe to Pro
Rusty
Greetings,
I've been using TurboCAD Deluxe for 2D work, and am fairly happy with it. I've been wanting to learn more 3D design, and just received a good upgrade offer for the Pro, or Platinum...
Greetings,
I'm trying to make some 12mm round cuts in Delrin using a Dewalt router. Life would be simple if I could find a 12mm ball nose end mill that has a reduced shank of 1/4", but I haven't...
