10mm belt nema23

[JAZZCNC]

Hi jazz, The belts are 10mm wide t5 20 tooth pulley,
This is a laser cutter running awc608 laser controler,

The steps it's set to now I can move back and forth nice, but if set them lower they just move 3mm and stall, so not sure if this is through psu needing bit more power, or turning amps up,

The 48volt psu I got as a ajust screw, if this is turned down to lower volt would it hurt the psu or are they ok,

Thanks jazz kev

Ok I see on the controller front and while I can't find the Frequency this controller works at I'm sure it will be more than 25Khz so lack of pulses shouldn't be problem. Still However lowering the MS shouldn't cause stalling motors provided you set it up corrrectly in the controller which might be your issue if not doing this.

The motors you are using are relatively high Inductance so will require more voltage to spin fast but still with 100mm pitch they should easily reach 500rpm if wired Bi-polar parallel.
If series wired then this could be your issue because torque drops away quickly as RPM increases and with only 36V may struggle to spin much more than 500rpm.

Do the Motors have 4 wires or 8 wires.?

hi jazz 8 wires wired parallel, the only settings that can be set in controller is calibrate the distance moved, table size, homing switches
I cut square 100mmx100mm and put that in till it gets to right um pulse, which works out at x 15.621760 and y 15.575712

thanks jazz kev

Hi Dean,

It would not be advisable to get the am882 drives and a decent toroidal psu (I guess around 60v, you have more experience..)?

I see that he had invested a lot in his build but got stuck with some crap drives, and he only needs two of them.

edit:

Kev, I told you about the importance of setting up acceleration. Did you get the idea?

From your controller manual:

【Max Acc.】: Acceleration when axis making accelerated or decelerated movement. Too a big setting may lead
to motor losing steps or dither; too small setting may cause slow acceleration and then slow
processing speed for whole image. For axis with big resistance, such as Y axes corresponding
with beams, typical setting should be within in 800～3000mm/s2 ; For axis with small resistance,
such as X axes corresponding with carts, typical setting should be within in 10000～
20000mm/s2;

With 100mm pitch then shouldn't need it. 500Rpm isn't diffcult to reach provided theres enough pulses.

Now what I'm not understanding is the numbers given.? 15.62 for 100mm of movement would suggest close to 205mm pitch with 3200 MS.
So to me there must be ratio going on somewhere.? . . . or the Belts are not T5.?

Yes all the settings in there are ok and as been altered to suit, all these do is if your cutting then it moves to the next cut, it accelerate to fast and lose steps, or to slow moving to next cut, the speed settings are when your in the layers, as fast for engrave slow for cut,
