Since writing my original post, I rewired the two Y axis motors to use the same signal wires from the motion card to the two different drivers, reversing the polarity of the connections on one motor....

So, got it built, everything connected using Mach3...slaved A to the Y axis. X on gantry is silky smooth, and one direction on y, towards the side that the motor is on....but the other way, in the...

lol...I'm OK with brutal...I knew I was buying low end stuff, and was purely for self-education...i was just shocked that without even any physical load the motors or drivers would be cutting out. ...

What's confusing me is that if it s the PSU that's too low, why would only one of the drivers shut down? I can't believe the PSU shuts down one terminal connection vs another, so it must be the...

Thanks, but that's not it, because Mach 3 keeps running, as does one of the motors. If I unplug and replug it back in, the motor drive that tripped resets and starts running as per the gcode...set...

Here's what I bought, if it helps diagnose the issue...

OK, so i tried again today, disconnecting the Z axis, running just X and Y. Set the max current on the drivers down to 2.8 amps. Both of them will eventually just stop, mid program. Unplugging the...

Hmm....okay, daylight is slowly creeping in...I just took a look at the PS and see it says 36V 10A on the side....so, yeah, it's too small to run all three at their "max" of 4A each...even at the...

This was really what I was asking in my original post...I did try this and it seemed to work a bit longer, but tripped none the less. The test program I'm running is a circular pocket just using...

Not fading...just stops working. Everything came as a kit, so I can't imagine I'm exceeding the power output of the power supply...36V, 350W supply...the motors are rated 4.0 amps....

I swapped the X and Z axis wires at the board...I don't think it's the signal from the board, as the blue light which flashes with each step stays on solid...it's the green light indicating power to...

Hello, been lurking here for years with aspriations of CNCing my RF-3), but never got around to it. Been using a 3D printer for a while, and recently decided to use the pandemic lockdown time to...

subscribed...my Craftex B1977 is a clone I think, so post lots of pics as you go!

I've been humming and hawing over converting my round column mill fro 2 years now...everything I"ve read has pointe dme towards 570 oz motors, using direct drive (no belts/pulleys)....looking forward...

Well, an abundance of free time over the holidays has rekindled my desire to cnc my mill...it is a round column mill, made by craftex:

Thank you both! Bubba, PM sent...

Thanks very much for taking the time to draw and post these plans!

Can anyone please direct me to or share some dimensioned plans/drawings for a direct drive set up for a RF-31 or similar mill/drill?
thanks!

Perfect Hoss, thanks...just to be clear, 570oz motors would be suitable for direct drive? I would prefer that to a pulley set up....

Thanks for your response...so i gather that these components are mismatched, at best, correct? I'm afraid the electrical specifications are lost on me.

If I might rephrase my question, what...

Can you qunatify this statement a bit? I'm not looking to set speed records, but dog slow isn't a goal either...

I have read so much that my head is swimming, but if I could ask for a straight forward question regarding opinions of the following kit for a G1006 conversion...
