a pity about auto transformers, because there are plenty of them for sale, and they're high-powered.

I'll turn to this:



is it insulated?



moreover, i found in my garage two insulated 400/240 - 110V transformers with a power of 1000VA with two 110V 2x4.26A outputs and can up to 5000VA for short time

 

so I'll go with

transformer 1000 VA : - motor 0.57 kw 1.6A 143V
                                - motor 0.57 KW 1.6A 143V

 transformer 1000 VA: -motor 0.57 KW 1.6A 143V
                                -motor 1.5 KW 3.7A 146V

transformer 3000 VA :- motor 2.5KW 5.4A 185V
                                -motor 2.5KW 5.4A 185V

does this sound right or is the 3KVA transformer too small?

 

ok thanks and how can i configure my axis display without dev install?
you can run fusion 360 for a 4th axis part....
always you have to do ist configure a 2D adaptive clearing and sort it in a round pattern...finish now you have a indexed 4th axis part

here is a 4th axis gcode:
 
 

This is documented here:

linuxcnc.org/docs/html/gui/gmoccapy.html...tabs-and-side-panels

You can replace the spindle box with your own glade file / function.

vtk which is the back plotter is undergoing extensive reconfiguring, so the latest stable had some issues in it that went unnoticed in certain areas. many things have been corrected in the develop version but a few still need to be sorted. one of the things was how the plotter draws and follows the program tool paths. hopefully this will be pushed and released very soon as i think most of it has been corrected but there are still a few bugs to sort out and testing is difficult without multiaxis cam available

I would also add that if it’s possible to use shielded motor cables, use them and tie the shield to PE from both ends.

It’s the switching noise from the drive IGBT.

You should increase motion blending tolerance (g64 p0.002)

The more accurate the tolerance -> the lower the speed.

For roughing operation (adaptive) such accuracy is not required. Try setting P0.05, this will smooth the trajectory and allow it to be executed at high speed.
If the acceleration of your machine is not high, then for roughing operation you can choose P even more.

In an older Probe_Basic version I adjusted the interface so that everything worked.

However, I don't know how to edit the interface in the stable version. I'll probably have to install the developer version again, which I don't necessarily want to do since the machine is currently in use.

However, I still have the question of why the 4th axis plot doesn't work, which used to work in the older version... my configuration has remained the same.
