Problems continue and don't know what to do

[Crazy L]

Hey guys, hope you all had a good Christmas.

Following your superior knowledge, I got everything working. I need to tweak the axis speeds though as in jog, it's all good, but if I rapid in MDI, they stall, but I now know how to do that.

I also have X going in reverse. So I have a question: When setting up the steps, when I tell it to move a distance and then it asks me how much it actually moved, should I have told it that moved in minus? I simply said how much it moved and didn't think anything of it at the time.

I got the spindle going with a bit of thinking. I hadn't enabled an output.

Anyway, a couple of tweaks here and there and she'll be all ship shape and ready for making stuff once again. I honestly couldn't have done it without the help you guys have given me.

I've written my settings down too, on paper, so should something ever happen, or I adjust something and need to un-adjust it, I have something to reference.

Happy new year to you all.

I also have X going in reverse.

Have a look at the active high/low settings for the axis. If they are not out of kilter with the Y and Z then I would just swap either the A+, A- or the B+, B- at the driver for the X.

If you have the Motor phases wired correctly IE A+ A- B+ B- and the drives wired Correctly IE: Step+ Step - Dir + Dir - then don't switch the active Hi / Lo because it can cause other issues with pulse edge etc depending on how drive is setup.
The easier way is to go into Homing / Limits and toggle Reversed, this will reverse the axis but not affect Pulse and Dir. You may need to toggle the Homing direction as well if it goes wrong way when homing.

No doesn't matter. only needs to know distance moved.

Thats always a good idea but when finished setting up also make a copy of the XML file which will be in Mach3 folder under same name as the profile name. Then if goes down at any time you just reinstall Mach3 copy the saved XML into folder and it will reload with all your settings ready to go.

thanks JazzCNC

It's been a while again as I had other things rear their head again, then this lockdown caper kicked off, and it's only now that I have rediscovered where i was at before. About to go and experiment with homing/limits

Thanks for all your help guys, I'm learning all the time.

I tweaked the axis stepping the other day to improve it a bit, making dimensions a bit more accurate. Upon machining a circle though, I have noticed it suffers at 3, 6, 9 and 12 o'clock, giving flat spots. Can I assume this could be a typical fault of the stepper motors or the board quality? Just a question really, trying to learn about this thing.

Have you checked for back lash?

[Crazy L]

I have not.
