We had purchased one of these mills, and of course it came without any limit switches or home switches. Does anyone have any recommendations for a kit or setup that would allow me to add the limit...

Thanks for the heads up! I did contact Leetro, but no one got back to me yet.
Mine doesn't power on at all anymore, I don't know what happened to it.
I'll wait and see what they say.

I'm looking for a replacement MPC6515, since it seems our current one has bitten the dust. Does anyone have any sources for one?
Thanks!

I really hate to have to bump my post, but here goes... I got the relays in. 4 of them in fact since they're insanely hard to find and I had to use google translate to order them from the chinese...

Ladies and Gentlemen, I've found the culprit.
It was indeed the relay. I traced the wire going from the motor's coupling, throughout the entire machine only to find it connected to a block which...

Good news then I'm almost there, by switching the motor cables from the drivers AND the terminals where the motors plug into a coupling (which go deeper into the machine and then presumably to the...

If that is the case, how might this have happened? since the machine hadn't been used or moved for a few days, then all of a sudden I turn it on and it does this. I'll try tracing the continuity on...

Would a bad relay do this? It seems the wires I've traced that I've switched around the UVW wires go to a relay which seems to be the device that switches from slow to fast speed after holding down...

Well I've switched the power cables that are going into the drivers, no change there, and since the problem followed witch whichever plug was on the Up/down (Y) axis no matter how I switched the...

I did switch the motors, and the problem followed to the other motor, so it's not the motor. I did the firmware update and it did to SOMETHING, it removed the slow jog speed from the control panel...

Was going to try this if the firmware thing doesn't pan out. I'll keep ya posted.

So far I've replaced the stepper drivers completely, no dice there, I tested all the power supply outs which all were good, tested everything I have access to up to the MPC6515 board. I've read that...

The only controls that I have access to are the control panel ones, there are no further software controls that I can tinker with since it's not mach3 or anything good.

I've posted before looking for advice on this problem, the one axis stutters and shakes when jogging or when running a job, after a process of elimination of power supply, drivers, and mechanical, it...

I don't believe it's static, since the day it failed, the problem hasn't resolved itself at all, I'm not using Mach3 or any software that I can change config files on so it's nothing I can test...

I did switch the cables to the motors around and the problem follows the plug, not the motor, so I know the motor is not the problem, not the drivers, and MAYBE not the power supply but I can't...

Allow me to clarify, I'm good with electronics, but I don't have much experience with this type of equipment.
So if I connect the power supply that is attached to the Y axis to the X, it still...

We've got a chinese laser that worked for about a month, then the one axis started stuttering (press the jog button and it vibrates loudly for about 5 seconds then finally starts to move) through...

Hi, we've got a cnc bed that's using two of these syntron sh-30806n stepper drivers, one of them went nuts one day and we're looking for a way to repair or replace it, however since none of us know...

I looked over the board, definately no ROHS here, every bit of it is obvious lead solder and no cold joints at all. It looks immaculate actually, never seen a PCB look so good.

Zax, Thanks for the link, I scoured ebay, but I was at a loss as to what to search for, I even browsed through just "step* driver" but I didn't spot that one, it "looks" identical, and I see I'll...

Jeff,
I'm still trying to source the part, I believe retrofit might be beyond my abilities, and option 3 isn't very feasible since it weighs about 700lbs. I didn't mention in any of my previous...

Here are the pictures of the driver, I don't see any visible damage, but I do have a guess on what happened. When this whole thing started, I opened up the back and found a copper standoff stud...

Well, that's not encouraging... The motors each have 6 wires, and I'm assuming the driver units are those two identical looking boxes. After closer inspection, the only markings I can discern are: ...

I appreciate the concern, but I took all the necessary precautions. Powered down inbetween switches. The pictures are dark, I've got to leave work now, but I'll be back in at 10AM, if more info is...

Okay, closing in on the problem here.
I'm gonna put the motor back in.
I switched sockets for the stepper motors, and then the X axis started acting the same way, switched them back and X is good...

I'm electricallyt minded, not so much for electronics though, so I pulled the motor out completely had to cut wires in order to do so because they fed the wire through a small metal hole, under the...

Jeff,
I'm not in the know enough to know mach3, I've heard of it, but don't know what it is. And in any case... I found the problem. I started pulling screws out and low and behold, the stepper...

Jeff,
I've checked every possible angle and point of contact, used a really slick dry film lubricant on the Y axis, and can move it with a small amount of effort when the machine is off, the exact...

We did a test engrave and no, any fine Y axis movements (front to back, I believe that's Y) do not perform correctly, it looks like chicken scratch. It's like the Y axis motor has no torque at all...
