OK so iv been trying to set up my 6040 cnc and to be honest i can run it and i have cut some MDF with it, but im not 100% happy with it. The problem i have is if i set the motor tuning to the recommended setting the steppers jam. To prevent this i have to run them at less than half the recommended settings. Here is a video of whats happening maybe someone can help,

hope some one can help
It would help if you gave some details about power supply, voltage, motor specs if you have them and driver.
That would be a start so people can make an informed opinion. ..Clive
Also do you have Mach3 set to mm or inches ?
yer sorry this is what i have

and this is what in the box and the steppers

i dont know if that helps.. i also have mach3 set to mm .
thanks for the help Mick
It looks like you have this setup;
3163B Stepper Driver
set to;
Dynamic Current = 2.5A
1/8 Microstep
50% Standstill Current
57HD5401-14S/8 Stepper Motor
1.8 step angle
6.6V
3A
2.2 Ohms
8mH
17kg/cm
4 wire
24v 8.3A DC PSU
1605 ball screws
And that being so, the settings you have seem to be okay as far as I can make out.
However I did a conversion of the motor torque setting and 17 kg/cm = 1.6671305 Nm, this is not so good but as your video shows they are not under load.
I think you could reduce the microstepping and see if that helps, remember to change the Mach3 'steps per' to match.
5m pitch
1.8 deg motor
1/8 microstep (8)
360/1.8 = 200
200/5 = 40
8 * 40 = 320 steps per
------------------------------
Reduce microstepping to 2 by setting K1 ON, K2 OFF
5m pitch
1.8 deg motor
1/2 microstep (2)
360/1.8 = 200
200/5 = 40
2 * 40 = 80 steps per
ok thanks ill try that. im rite in thinking at the moment they are both set to on. so all i need to do is switch k2 down on all three . Then change the steps per to 80 . I do have 3 of these i could try and see if its any better if that dose not work .

The problem with these motors in the inductance is far too high. Check these out:- http://cnc4you.co.uk/resources/60BYGH301B.PDF and see the difference, the motors you have require a much higher voltage to drive them. I would be selling them and getting some with lower inductance. ..CliveQuote:

but i was thinking i could just use the stepper motors if the ones im using arnt up to it. So is this not the case ?
Are you saying my power supply is not upto the job because if thats so could i not just swap it out for the 36v one i have ?
On the picture I looked at it says on the terminals 24V, Gnd, so are you sure it can be powered by 36V ? if it can then it might be a good idea to try the other supply.
I agree I have a feeling that those drivers are only OK up to 24V So unless you like magic smoke don't go higher. CliveQuote:
