General Mach Discussion / Random jolts?

« on: March 19, 2018, 06:55:25 PM »

Hi all I am having an issue with my plasma having random “jolts” while the motors are running. This is happening whether I’m manually jogging, or running a code. The motors seem to jam up for a second, and jolt back and forth in both directions. It is completely random. Another thing I’ve noticed today, while my plasma is sitting idle, it’s making the motors move very slightly in both directions. This is also random.

I have a gecko g540 board and I have been running great lately, this is a new occurring thing since this morning. I haven’t changed my setup anyway.

I’m going to keep fine tuning the setting to make it work better, but it’s working great.

Thanks again for all the help, I appreciate it.

Ever since I adjusted my Z axis motor to run at 15:15, it’s running perfect. I’ve been cutting some 1/4” , 14GA, and 10GA mild steel and it’s awsosme

Okay, so I’m at This point trying to get my Z axis to travel at its maximum speed before it makes an error?

Ok, thats possible - try making up some simple code to rapid (G0) the Z axis from Z0 to Z2 (or whatever travel you have, run it maybe 10 times starting from Z0 at a known position and at the end go to Z0 - is the axis in exactly the same position it was at the start???

If you are losing steps it could well be this, plus, when running THC you need to know that the normal acceleration curve is not used, THC moves on Z are more like BANG-BANG-BANG really fast moves are needed here or by the time the Z has moved the torch is elsewhere

I think there its a setting called THC-Rate - its a % of speed, try going low and working up, however i cant remember if this is a generic Mach3 setting or one specific to my screen set/THC system.

Test for lost steps first


EDIT

just saw TPS' reply - thats the box i mentioned.

I ran a code

G0 z1
G0 z0
G0 z 1.5
G0 z0
G0 z 1.3
G0 z0


Ect.. maybe 25 times over and over. Z Axis landed in same position every time.

I will mess with my setting on Z axis tuning,

Thanks

Okay sorry about this I’ll worry about the PROMA thanks

I believe the Z axis is losing its steps. Or something in this nature. I have my Z axis tuning : velocity is 15 and accel is 1. It is working with the PROMA just kind of weird. Needs fine tuning I think

So, I fitted 2 switches to manually jog Z, it did the same exact thing that the proma was doing, so I adjusted my Z axis motor tuning as maybe it was losing steps? It is working perfect manually, I am going to hook the PROMA back up and try it now.
