On going chinese 6040 problems

Ok I'm lost now. Are you saying the board I'm using won't take 36v or the drivers that came with the kit won't take 36v

Ok for the sake of clarity I take it you have two setups one purchased with the cnc and the other which is a set of drives and motors and a power supply is this correct. .Clive

Yes that's correct
I was going to make my own so I got all the parts together to make one. Then I found I don't have the time to prototype parts. So I thought I would buy one. . The photos and video are of the one I got form eBay. The link to the aliexpress is a kit of electrical parts I have that for the one I was going to ( May still do) make. But I can use the parts on the other if I need to. Not sure about the sub Bob now thow as I have a dedicated pc with a PP. Hope that's abit more clear. Thanks mick

Mick In the absence of the master's on here (I am sure they will be around in a bit) let's see if you can get your original kit working. Frist alter the vel in Mach to say 1500mm/min and try that. (you have it set for about 2000mm/min).
.
The other kit you have bought is better but not good. You need motors with low inductance. The drives in that kit will accept up to about 48V which is better and you could use them with the power supply from the kit.

Don't get despondent there are plenty of people on here to help. ..Clive

Hi Clive. I know the kit I have is not amazing but it's all I could aford at this time. I'm not too worried about my set up as I have it running ok tbh, just not at the seeds they say it will run.

At the moment I have it set like this 320 - 1000-100. And it runs ok just a bit slow. This is fine for now as I'm just learning. But if I try any higher like say 320-1200-150 then it starts to randomly jam. At 320-1500-200 or higher it will jam all the time. I'm guessing the recommend setting are a sales lie by the eBay seller and not what the electronics are up to.

But I would like to track the fault down so I don't junk what I don't have to when I want it to run faster.
I'M thankful for all and any help I get on here.

Mike Are you saying that your running at 1000mm/min on one axis and slower on the others? ..Clive

No. X nY at 320-1000-100 and Z at 320-700-100

No. X nY at 320-1000-100 and Z at 320-700-100

Mike Is that code for steps, vel,acel ? ..Clive

yes Clive the manufacture instructions say to set it to

steps = 320
velocity = 2000
acceleration 200

but if i go anywhere near this it stalls

i have to set it to

steps =320
velocity 1000
acceleration 100

and at this i still get a bit of grinding sound some time.
