Call Fanuc they have free support, even on something this old. It’s probably an K relay option that needs to be turned on.

I've used the UCCNC on many machines mostly AXBB-E and UC300.
First using a wireless pendant is a poor idea, there is a reason it is frowned upon in industry. Wireless controls are subject to...

Based on the location, I'd say it is a 50v Bypass Capacitor. If you pull the data sheet on the IC next to it, then check the traces to see if they route to the power and ground pins. If it does then...

So the final solution ended being the Z was disabled.
The Machine a Mori MV-40E doesn’t have hardware disable switches on the panel so the Z is on a custom screen. The customer swore he didn’t touch...

Found it,

I have not, can you provide a little more info G108.2 are you talking about in the ladder?

I did try replacing the A20B-2901-0700 (Servo interface module) and A20B–2901–0340 (Servo control...

Hi All,

I have a customer who has an old Mori MV-40e which uses a variant of the Fanuc 21-m. Any axis connected to the Servo 3(Z Axis) port on the A16B-2201-0721 card results in the DRO changing...

I would check the bulkhead connectors they usually oxidize causing them to heat up and burn the insulation off the wiring. The motors are a weird 3/8" shaft Nema 34 and only 380oz-in, you may be...

I'm working on a Gerber 408 for a customer that doesn't recognize when a job is sent to it. Everything else seems to be working correctly. I can align the machine, run the test job, passes the...

Hi all, I have a customer who crashed their DMS 5 axis router and to get the machine off the part they loosened one side of the gantry. The machine doesn’t use dual homing to self square though the...

If you use steppers make sure to use closed-loop steppers with the feed rates of this machine. You would be better off swapping from the OEM motors as they are very expensive to replace like $2000.00...

Does anyone have the lead screw pitch so I can calculate the steps per rev on my 408?

That should not be a requirement, the machine should be disabled if the computer is powered off or the USB cable is unplugged.

The BOB should not have the outputs floating, they should be at...

No,

I'm powering the C10 with a dedicated 5V supply. I would encourage you take a set of devices from stock and see if the issue is repeatable.

1. Provide 5V to the C10 and jumper the enable....

Hello all,

I'm putting together a CNC Mill using the CNCDrive, UC100 and CNC4PC C10 Bob. The firmwware on the UC100 is for UCCNC and it's the latest version.

The issue I'm having is when the...

Mactech I did search and your largely quoted response doesn't even align with my questions.... Was this intentional or supposed to be another post?

I went through the settings on my drive it shows 167v on the DC bus. Which is roughly 120v x 1.4

So, a 220v spindle will have lower AWG / mm^2 wire in the windings vs the 110v?

Eldon,

So you think I could get 800W in the 12k range instead of at the 24k.

mactec54

The specs on the name plate of the VFD defines 110V in/out.

I used a FLUKE 73 Series III, to measure the between WV and UV both indicated 120v AC from phase to phase with the motor...

Oh CNC electrical gurus please help a poor lost soul.

I accidentally ordered a 220V 1.5KW spindle to replace my 110V 800W unit.

I have a HY 110V 2.2KW VFD so that is from a current current...

Ah, yeah I'm running the latest versions from that page. See I posted them in my original post. Thanks anyways.

I just installed Smooth Stepper and I can't individually tune my axis. I need to limit my Z Axis to a lower feed rate. Is this normal behavior?

I just updated to the newest version of mach3 to see...

I'm looking to pulse an output on enable, the output is tied to an amp enable/error pin that's shared with an input that detects a faulted amp.

So, 5v = Enable / Amps OK
0v = Disable / Amps Fault

I have the machine up and running, but on reverse direction I get a lot of noise on the X Axis. The Y & Z seem OK, would it be safe to say the belt is still a little loose? I, see a 10v dip when all...

I have a CNC Machine I'm trying to refit and the encoder is a 2500line Danaher mounted directly on the ballscrew and the motor is coupled 1:2 via a kevlar belt. Do you see any issues with that? It...
