Everything with the machine works nicely except that slow (G0) issue which really doesn't bother me that much.

At this point, I am going to concentrate at other issues and get back to it when I have a bit more time.

I'm pretty sure the G0 is working fine, and it just appears slower because it's not cutting anything. There are no controls or settings that would slow down rapid moves.

That's the name of the profile you are using.

As mentioned, UCCNC has two homing speeds. It moves at the first speed until the switch is tripped. The actual home position is when the machine backs off the switch, so you set the backoff speed slow. This let's the machine home fast, but still be very accurate.




This has nothing to do with UCCNC at all. You have your feedrates set wrong in V Carve.

Regarding UCCNC "units".

UCCNC does not support G20/G21 (inches/mm) conversion, so it runs in whatever units it's configured in.
This is done with the steps/unit setting. If you enter the number of steps required to move 1 inch, then it's setup in inches.
If you enter the number of steps required to move 1 mm, then it's setup in mm.

It's important that you use the same units of measurement throughout the program.
This is no different than any other control program.

That is very different from other controls then if it is not supporting G20/G21 that's not very good at all, support for G20 / G21 is a normal standard code so there is no reason for it not to be supported

I would guess it would be easy for David to check by looking at the feed rate on the controller screen. I couldn't see the screen in the video but like I was saying he can just enter in the MDI G0Y10X10 or something similar and watch the feed rate on the screen and see if it says 400ipm or a different value. It looks to me more like 100ipm to me but maybe you're right and it just looks slow because my rapids are 900ipm.

G0 X10 Y10 will move at 400 x 1.41, as both axes would be moving at 400 each. Provided he's starting at 0,0. But he probably needs to make a longer move to see it for more than a brief moment.

Summer, family vacation, business trips, kids, paying bills ........

I will soon do one more project in wood and then move on to cutting metals.

The final wood project is about:

"Something Grand"

Good to see you back, David. Looking forward to seeing what's to come.

After all your inputs during the electrical assembly and the bottle
necks I experienced during the test runs, I decided to redo my
electrical box to bring it up to code and revise some shortcomings.

First of all, the RJ45 connectors I used for servo data signals proved
to be somewhat fragile and sensitive to vibrations of the machine.

The power-in side in the box was too tight as well. Additionally, there
are no power-ins and outs for the three relays which the BOB provides.

Other than that, everything with the e-box worked actually quite well so
far and I want to incorporate all of that during this revision.

I will be using the old-fashioned and tried and true DB9 connectors in
the new box for data transfer to the servos.

To start with, here is the new schematic diagram for the new
layout, derived from your suggestions as I understood them.

Please let me know if this would correspond with the code:
