    Re: Nema23 Stepper motor issues

    So to compile what I should do in terms of calibration:

    Set all motors to 3.3A
    Set all motors to 1/16 microsteps (to smoothen the movement?)

    Is that correct?

    I will do what you wrote,...

    Re: Nema23 Stepper motor issues

    Hey, did you see my other question regarding the motor moving after I stopped pushing the button, like it just keeps going for a bit after I release the button. Do I correct this by...

    Re: Nema23 Stepper motor issues

    Okay, so what can create backlash on only belt driven machine? Loose belts? I'll tighten them then. I'll make sure everything that even remotely touches the motor is fixed in place.

    By the way, do...

    Re: Nema23 Stepper motor issues

    Huh backlash is something new for me. How does it actually work, I mean the gap means lost steps or what exactly? Right not it's just an axis, I have dismantled the plasma so we can just discuss in...

    Re: Nema23 Stepper motor issues

    Oh right. It's a plasma cutter.

    As I said, I don't know what to set up in motor tuning with acceleration/speed - is there an universal value for these motors? Because as I said, they're not...

    Re: Nema23 Stepper motor issues

    Ah so 40 pulses per mm = 40 steps per mm? Got it. I was wondering because everyone here have astronomical numbers like 3200 or 6400 or even more steps per mm, and will the 40 steps per mm not be...

    Re: Nema23 Stepper motor issues

    So I'm thinking is the cambam post processing in any way responsible for changing the size or something? Is it even possible?

    Because I might have worded it wrong, but it's like this - if I...

    Re: Nema23 Stepper motor issues

    It turns with no load without issues. The moment it gets a shred of load it stops and starts...buzzing, I guess. I also swapped the entire motor, since I had a kit for 4 axis. The same with new...

    Re: Nema23 Stepper motor issues

    Huh you quoted your entire post, and I was thinking you just quoted me and said "it's not that hard", heh.

    Ok, got the pitch. So you're saying the shaft is connected to the screw, to the coupler?...

    Re: Nema23 Stepper motor issues

    Thank you for your insight.

    I'm guessing it's 3200 microsteps and that's a typo, right? 200*16? But what's the "pitch of the screw"? I'm not a native english speaker, that's why I don't know these...

    Re: Nema23 Stepper motor issues

    I actually did get that working, so everything is moving. I'm just curious as to *why* did it not work - but I swapped the drivers and everything is ok now (with the older ones, I think 5.6A instead...

    Oh, yes, sorry, I forgot to write this - I have swapped each and every driver, cable and whatever there is from working Y and Z to X. The X driver worked everywhere else, the Y and Z didn't work on X...

    Nema23 Stepper motor issues

    Hello,

    First off, sorry if that was already covered, I have searched for the serial number of my motor and stuff, didn't come up with anything. Before I start, I want to say I have read a lot...
  14. Re: The profile of my cut is not straight, plasma not strong enough?

    Ok, so I made cambam run in the CCW direction, gave it a 110 amps and it didn't do it right, but it made it better. Not sure what to make of it. Oddly, my machine doesn't do exact circles, it bends a...
  15. Re: The profile of my cut is not straight, plasma not strong enough?

    Ok, I'll just make cambam do an opposite movement and give it a bit more amps. Thank you for your help, I'll tell you tomorrow if that helped :-) I'll give you all the details tomorrow aswell. Thanks...
  16. Re: The profile of my cut is not straight, plasma not strong enough?

    Wait, I'm not sure I explained what my problem is clearly enough. Or I'm not understanding the answer. I'm not even an amateur in this, I just happened to be there when my friend got his cutting...
  17. Re: The profile of my cut is not straight, help needed

    Thank you very much, I posted a response there, we might aswell transfer our discussion there :)
  18. Re: The profile of my cut is not straight, plasma not strong enough?

    Hello, thank you for your reply.
    I'm not sure about the direction of the cut, I think it's CW (according to cambam). Yes, all is leveled in relation to the torch, besides even if it was a bit off, I...
  19. The profile of my cut is not straight, help needed

    Hello,
    I have a problem with my plasma cutter, running on mach3 software. Everything is leveled and straight, it's ok when I cut 2-3mm steel, but when I go to 10mm, it rarely cuts it like it should,...

  21. Re: Mach 3 - correlation between steps per MM and size of the table

    I'm gonne get a picture of the machine and post it here sometime tomorrow/day after that, when I get to the workshop. Thanks for the explanation!
  22. Re: Mach 3 - correlation between steps per MM and size of the table

    Not exactly. I was digging through documents in the workshop to see if I can find something about the machine and I found a note about the motors. Would that help in establishing steps per...
  23. Re: Mach 3 - correlation between steps per MM and size of the table

    Well I set up the steps/mm in motor tuning section, no? Oh that's called DRO, ok. So yeah, if I set up 13/26 for X/Y steps, DRO displays from home to 2000/1000. But when it's set by the mach3 setting...
  24. Re: Mach 3 - correlation between steps per MM and size of the table

    Will try what you said, but I'm not sure I explained my issue correctly.

    There's this window where the "zero x/y/z" and units are, right? When I home the machine, it all says 0 and everything is...
  25. Re: Mach 3 - correlation between steps per MM and size of the table

    Greggv:

    Yes, I used this as I mentioned. I put in 5 cm, it moves say 1cm, so I tell it it moved 1cm, then I do it twice more just to be sure and it sets my steps per unit to 267. Thing is, if it's...
  26. Re: Mach 3 - correlation between steps per MM and size of the table

    Thank you for your input. However, like I said, I'm new to all this and please explain like you would to a three year old (heh). What screws do you have in mind? Where would I find them and how to...
  27. Re: Mach 3 - correlation between steps per MM and size of the table

    Thing is, if I program a circle to be 50mm in diameter, I need mach3 to move correctly, as in movement in X has to show distance of 50 value. I have set up soft limits, they all work fine in my...
  28. Re: Mach 3 - correlation between steps per MM and size of the table

    So I'm right that steps per milimeters tell the software how big my table actually is? Your advice is to remain at 13 steps per MM and adjust the velocity/acceleration? I tried that a bit (no...
