Hi all,
This issue has been haunting me for about a year... I have a Redsail X700 with a Ruida controller, running with RDWorks.
When I do large engrave job, the x axis slowly starts to drift to be offset, as it progressively moves down the Y. You wouldn't be able to tell, until you go to cut it out. The cut is accurate at the bottom of the project (closest to the last engraving) then slowly becomes terribly offset toward the top (furthest from the last engrave). The X
I've worked through a lot of possibilities and I think it has to be a stepper, voltage or software issue... this is also happening to a couple of machines of other people I know, who run various versions of rdworks. It is certainly not mechanical, as I have checked all belts, wheels, made sure no movement is happening on the table, and the beam is focused everywhere. I've also ran the program in many different ways, running the engrave and cut as two separate jobs, running it as Udisk, all one layer, all one jpeg, multiple layers, putting it all in a rectangle "frame", etc. Same result. The same thing also happens on other large projects.
I have attached images so you can see what I am talking about.
Does anyone think it could be a voltage problem? I see some potentiometer dials on the drivers that are connected to the x, y, and z stepper motors. Image below:
Maybe I need to just replace a stepper driver or stepper motor? Anyone solve a similar problem to this? Any idea how to fix it?
Thank you for any help you can provide!
Sincerely,
Jon
