Anyone else here using an AXYZ CNC router? I've been having some strange issues when it comes to 3D surfacing tool paths. Everything looks good in Fusion, and they also check out fine in an online G...

I am trying to run a parallel surfacing path on an AXYZ router, and I can't figure out what is wrong with either my code or the machine itself. I'm doing the toolpaths with Fusion360, and the...

I've been looking all over the internet trying to learn more about subroutines and while I feel I have a decent understanding of how they work, all the tutorials I've looked at seem geared towards...

I typically use the cycle stop button, however the way my drivers are wired into the UC300 board, if there is a fault from one of the drivers, it triggers a generic e-stop signal to the software. It...

I think I may have discovered an error that could be responsible for the loss of position. Usually a servo fault will show up as an error 002 or 000 on the driver, and requires a power cycle to clear...

I've tried that trick of selecting the first edge, then re-selecting and getting the whole closed loop, and that has worked great on other parts, but not here. I managed an odd workaround where I...

Fusion is giving me some more issues when it comes to selecting contours for 2D cutting. I got some great help here before when I was having trouble selecting a chain to cut letters, and in other...

Yes, I measured the voltage and it fluctuates by about 10-15 %. Noise could be a factor, but I don't have an oscilloscope to check. I was reading through the other thread about Modbus control, and...

I've been troubleshooting the speed variation with Arturo from CNC4PC as well, and changing the frequency to 800Hz in UCCNC helped (VFD is 400Hz) in getting the set speed closer to the actual speed,...

I've checked the connections for the encoder and everything looks fine, but I'm not sure how I'd test them further without an oscilloscope.

As far as running unattended, I'm not planning on...

I'm sure most of us have at least one crash under our belt, and hopefully we learn something so mistakes aren't repeated again. The first big crash I had was carving a 3D tool path with a 3/4" bit....

As a quick test I removed the wires from the second relay so it can only send an M3 forward signal, and that did the trick. I would like to have the option for reverse, but for now at least I'm up...

So I've plugged the db25 into the other port and the relays are turning on and off with m3 and m5. Something must be off though cause both relays turn on with an m3 and the spindle won't start....

The relays aren't turning on. The led in UCCNC diagnostic light up though, both for direction and pwm (it flickers when not set to full speed, I believe this is how it gets the board to vary voltage)...

PMW pin 14
Direction Pin 16

I'm in the process of installing a C69 PMW board on my CNC to control a Delta VFD022E21A. I've got the board wired up and I should have UCCNC configured correctly, however when I switch the VFD to be...

George is using TBI ball screws and SBC linear bearings. Hiwin may be compatible, but you should double check. The ball screws George chose don't have good wipers, so if I were doing things over I'd...

Air pressure or oil pressure would work to keep debris out, unfortunately there's no easy way to hook up a hose to my ball nuts, there's very little clearance even for regular maintenance and...

I've been regularly cleaning the screws, but it builds up quick enough that I want to find a better solution. At first I was re-lubing with white lithium grease as recommended, but that creates a...

Has anyone had long term sucess using a dry lube like silicone or graphite for ball screws? I've had issues with a thin grease film being a dust magnet, and have had to clean a mix of grease and...

Has anyone tried using dry lubricants like silicone or graphite? A thin film of grease or oil is a dust magnet, and in a wood shop there's no way to avoid that. I've noticed buildup from the dust and...

If you loosen up your tolerance requirements you might get by. Nothing wrong with rack and pinion for some machines, but you can't expect to hold the same tolerances as a ball screw. I also wouldn't...

I'm still wrestling with some issues with Fusion360 tool paths and UCCNC. I've enabled smoothing set to .005" or higher and played with CV settings in UCCNC with some success, however one common...

I tried to use 3D contour and I get an internal CAM kernel error. Trace gives me a functional toolpath, but it's inefficient. Here's a link to the model A360

Include 3D geometry works well for making a 3D sketch, and it's much easier to select for making a tool path, however Fusion still wants to re cut the same path and still has several retracts. If I...

I'm trying to find a better way to make tool paths for this part. Right now I'm using trace to select all of the 3D arcs, however it leaves me with tool paths that overlap already cut sections,...

Georges extrusions seem to be a little straighter than 8020, but depending on table size I'd say it would be reasonable to expect extrusions to be out between .005" -.01". True that some errors can...

They would likely be metric like Georges other profiles. One thing to be aware of is that an aluminum top won't be perfectly flat. Not a huge deal if you put an mdf spoil board on top, but it would...

There's a couple little tweaks I'd like to try and make to the UCCNC post processor in fusion. The first is that it automatically adds a G54 command at the beginning of the code. For my purposes I...

For some reason fusion doesn't want to open the file. It gives me error message: OK
