Hi, I'm trying to wire-up LEDs on my control cabinet to display when a home/limit switch has been deactivated. Will either of these circuits work? Any grounding issues I should be looking out for?...

Has anyone created a 3D model of the PM-728vt?

My mistake. I meant ball screw not "hall" screw. Butterfingers on the ipad keyboard. The kit I ordered was the one from Precision Matthews, same as you. Still waiting.

I just got a new PM-728 as well. I’m waiting on the halls crew kit. Has anyone drawn up a 3D CAD model of the 728?

Thank you, very helpful.

Thanks again. Here is the PSU I was thinking about...

Thanks for the help. If I were to go with a linear/unregulated power supply (like an Antek torod/rectifier/large cap PSU), would I still need the shunt regulator?

I'm building a CNCRouterparts.com benchtop pro 2x2 router. I have an MX4660 and 4 570oz Kelling steppers rated at 5A each. My power supply is a switching unit that is rated for 48VDC at 10Amps and I...

I’m interested in the linear rail mod that Scott from Benchtop Precision did. Does anyone know what the weight of the bare column and z slide are?

I also found Hwin block and rail here ...

What are your opinions of the HGH15 blocks they sell on Ebay versus the ones from Automation4less? Are the Ebay blocks counterfeit or cheap copies? What about these...

Hoss, thanks for the quick reply! That was the first thing I looked for, but all of the lock handles,screws, etc. were taken off prior to putting in the oil channels. Double-checked to make sure the...

I'm looking into linear rails on my G0704 Z Axis. I would rather not put out that much cash for an upgrade, but I cannot get my damn Z axis gib to fit anymore. I removed the column to machine some...

Can anyone comment on this diagram? I believe this will work, but want to confirm before I bite the bullet and lay down $250 for PMDX hardware. Any help is appreciated. Thanks guys.

Neilw20 and Dickeybird, thanks guys for the quick and helpful input. I currently have a KB SI-6 board sandwiched on top of the KBMM-125. I believe this provides the same degree of isolation as the...

Anyone aware of an alternative way to control spindle speed on a benchtop mill? I have a KBMM-125 controller with a Weiss 1.1Kw DC motor that I want to control with Mach3. My machine is a G0704. I've...

Thanks! Fastest1

What value are those fuses? I'd like to put a normal size fuse ahead of the MX3600 (between it and PSU) so it would blow before the SMD fuses.

What fuse did should you use for the DC in for the MX3660? I can't find anything in the manual that says what amp rating should be used. Should I use 6AMP or 18AMP or ? I'm planning on running 2 x...

Atmosphere... dig it!

All great comments and advice. The switching power supply I have is a Sola industrial grade supply that is DIN rail mounted. I may just go with a big linear, though. I was just hoping to keep my...

Will G201 drives work with a switching power supply (24v/10a)? Would it help/hurt to put a large capacitor on the power supply output like you would in a linear?

Anyone still trying to get their money back from DeWayne Harlow?

Hi,
Same here. My girlfriend is an attorney. She's looking into ways to approach the situation with Mr. Harlow. I'm not sure if it's feasible, but I'd like to get the refund plus compensation for...

Hi all...

I hate to weigh in on this one too, but I will. I too am waiting for a refund from DeWayne Harlow (Cncbridges). I paid for a base and z-axis well over a year and a half ago. I was trying...

Has anyone received a table yet or has everyone given up?

I was hoping we'd have some new pictures up. I'm starting to get a little nervous.

I’m finishing up the flood coolant table I’m building to fit the X2 upgrade table and Z-axis I ordered. Does this sound reasonable? 36” wide by 65” long coolant table with 3/8” carriage bolts...

Can I control my Gecko 201 drives with an automation direct (Koyo) DL05 or DL06 PLC?

Has anyone ever tried to interface a Pelco CCTV keyboard to Mach? This seems like it wouldd be perfect as a pendant controller. It speaks ASCII, uses RS422 (and RS232 I think) interfacing, and it's...
