running mach 3 with a usb to parallel adapter

[JAZZCNC]

before jazz and the rest of those out there that hate the chineese cnc range of machines sorry it's a fait accompli I am only interested in constructive comments on questions asked not my choice of machine.

How Rude.!!!. . . Did I say a word about the pile of shite.?

The UC100 is ok but it's still USB based and therefore will at some time have same power dropout issues lots of USB based devices encounter. Esp with a Laptop.!

For spindle control thru software you'll need speed control board or BOB that has one built into it. If Chinese machine came with the cheap Nasty DC spindle then chances are it won't have this and speed will be controlled directly from the DC speed controller with a Pot.
If spindle is AC and controlled with VFD then you may have BOB with PWM output so can control speed using this.

Sorry jazz I'm new and before I joined I looked at a few threads in which you always popped up with scathing comments about the Chinese shite as you put it. I know it's not the best but it will do what I want it to do I was on a limited budget.
as for the laptop I went through the power features and disabled them all, the flow of data will probably still be interrupted every so often but the UC100 should cope with that.
the reason for the uc100 as apposed to the various other methods out there is ease of fitting and not wanting to open up the control box.
looks like the spindle is a cheap and nasty DC one but should be a lot better than those on the 3040, I'll live with the spindle being under manual control, if the speed can never be controlled but there is a pin to switch the motor on and off I'll see if I can make up a relay circuit to control the start stop of the spindle.
I have at least got a pot and herz digital readout on the control box I'll learn.
just got a set of diamond shaped cutting bits for the Cnc came from China so there is no knowing the quality, anyone know where I can get better quality bits must be diamond cut 2mm or a bit less I'm cutting carbon fiber up to 5 mm thick.

It's ok no offense taken my skin is a little thicker than that.! My Scathing of the machines are based on experience repairing or helping others repair them so it's very valid IMO. BUT if you had looked hard enough you'd seen I've also said many times they are great learning tools just don't expect the world from them as they are not strong enough and component quality is poor so they wear quickly.

Regards the UC100 and USB drop outs then it will still happen from time to time as it's power based issue with USB and the UC100 draws it's power from USB so the data buffers won't make any difference. This happens on other USB based Motion control devices but most allow power to be drawn from an external source and it's avoided.
Often people don't know it's the USB causing the problem and just blame Mach3.!

Kendrick, I do not think your spindle is DC, changing the frequency on your vfd will change the spindle speed, so it must be a 3 phase spindle motor. Remember what I told you last night, spindle speed is pairs of poles x frequency,
ie vfd frequency say 400hz (cycles per second) x 60 (seconds to minutes) = 24k RPM. This is a little higher than the actual speed due to slip, but is near enough for what you need. Ihope that makes sense. G.

Easy to check Kendrick just take the connector off the spindle and if it as 2 wires it's DC, 3 wires it will be VFD/3phase like Geoffrey says. Looking at your other post I agree with Geoffrey it looks like VFD control panel.

Fr the power problems with the usb what about a powered hub then the usb power is not coming from the laptop.
The spindle has 4 pins coming off it more than I would expect from DC maybe brushless with a backemf sensor wire.

See in this other thread; http://www.mycncuk.com/threads/8457-...7150#post67150 too many threads for same thing.

Your Correct no point having 2 threads open for the same Cnc. This threads problems have now been sorted, can any future comments be passed to a more generalised thread about any problems I have with the 6040. Go to

Kendrick, you DO NOT have a DC spindle. G.

the 4th pin will be earth or not even connected ..Clive
