My Cheapo Chineese 3020t mini CNC Build (more like improvements) leanring all the way

[ravihotwok]

Managed to find a quick hour to do a bit on the machine with not the best results :-(.

Anyway I have wired up the limit switches and installed a second cable track on the opposite side to the motor cables to try and keep them separate. I have also drilled and tapped some holes to help clip the cables nice and neat

[ravihotwok]

I labelled each of the limit switch cables only to find I did the wrong lol, only need one cable per axis (2 switches)

Plugged it all in but its still not working correctly, motors seem to stop intermittently and something up with the y limit plug socket in the box.

I have not done anything to the settings apart from set the units per step which seem to be working now (when the motors don't stop)

I have sent an email to planet cnc and will do some more investigating tonight. Very frustrating as its starting to look really neat, just got to make sure the hardware has been assembled correctly

All a learning curve , be it a VERY frustrating one lol

Cheers

Right chaps, had a bit more time to play with the machine and iron out some faults, it appears my motors seem to stop working off their own accord, if you jog it one way then it move fine until it meets a slight bit of resistance, then it just stop's, but makes a horrible noise and tries to move each way slightly. My motors are anchuan 57hd0401-15sb. Im hoping that this is due to the severe lack of torque? My theory was to buy a new set of motors anyway with my installing the larger spindle, so I may purchase just one new motor to clarify that the low torque is the problem. Anyone had any experince with this type of problem?

You would have thought even craptastically weak motors could move an unloaded x axis back and forth.

Seems likely to me that you may have some binding going on. Does it happen on all axis?

[ravihotwok]

Morning Zee,
yes it does mate. I took the motor off the axes and it spins freely, but if you apply your finger to the output shaft it causes it to go mental

I spotted on another site about the motors something about these being 110v?

will try and find out

[Zeeflyboy]

That's a bit disappointingly poor! even a little cheap nema 17 on my 3d printer driven from an onboard driver won't do that.

you may need to look at upgrading drivers as well/instead of motors... seems like they aren't giving the motor much juice if they stall that easily.

do you know what drivers you have in there at the mo?

the motors won't be 110v, if anything they'll be talking about the psu input. most switching psu i've seen these days are 110/220v but some do require you to move a jumper.

one assumes if yours was set to 110v it would have gone pop already on 220v.

this is what I have mate
