Thanks, I will take a mental note to download once it becomes a stable release. Ger21, your endorsement of UCCNC in previous posts was one of the main reasons I made the switch!

Thanks all, I will turn it on and give it a shot.

Ok thank you very much!

In Mach3 I was told not to use backlash comp when in CV mode. Does the same limitation apply with UCCNC? Just switched over yesterday.

I have a simple touch plate where an LED lights up when the tool makes contact with the touch plate. Mach 3 had an offset for gauge block height and I just switched to UCCNC so I am trying to find...

It so happens that my new 80mm water cooled spindle is almost a match to the ID of 3” PVC pipe so I decided to make a dust boot. I used what I had on hand which was a 45 and straight pipe. I don’t...

Thanks all for your comments and recommendations, they have been helpful. I will be using shielded cable I just need to get things running before it arrived. It’s not very elegant but I have my...

I may be overthinking this because I regularly work with large VFD driven motors but is protection from common mode voltage needed for VFD spindles (I.e. shaft grounding) or is that generally not an...

Good to know, thanks!

I have a g540 that i want to connect to an existing stepper in bipolar parallel. the motor is rated at 4.2V 2.8A 305oz on the data plate (8 wire motor). I know if i wire it in bipolar parallel,...

i bought a 48V power supply off amazon (48V, 350W, 8A) to run my G540 with 3 stepper motors. i read some information from Gecko that they like unregulated power supplies because they absorb voltage...

i decided to replace my hobbycnc controller with a G540 (no issues with the hobbycnc board, just wanted to try something different) and i got everything wired up and have a green light and have...

that fixed it! i ran it all the way up to 120 IPM with no hiccups whatsoever. I am still puzzled why Mach 3 would be sending any step to the motor considering i have the backlash on that axis set...

yes backlash comp is on but currently set to 0 for y axis. let me turn it off completely and see if that changes anything. thanks for your help!

removed the z move and it still stalls. here is a photo of the code. it line 600 that it stalls on345100

yes i tried slowing acceleration down to half and it still did it. Sorry i forgot to mention that. there is a z move the line before that move but not during that move.

Ok i've got a real head scratcher here. i built my machine about 6 years ago and it has mostly been a fun toy and learning experience. it has its quarks and so anytime it did something strange...

So the encoders themselves seem reasonable, but don't i need an additional interface board, or can I tie them directly into Mach3 somehow?

I don't want to push the steppers faster than they are capable of, but it would be nice to have the extra peice of mind of stall protection, as you never know when something might go wrong. ...

I have run into a few instances with my machine where i had a motor stall that could have been disasterous if i had not been right by the machine (caused the router to plunge collet deep into the...

Yeah, the motion has smoothed up alot, i haven't run any code done with arcs yet, so i dont know about the crop circles, but i found the setting referred to, and im sure it will fix the problem.

What depth of cut do you use?

Oh ok, thanks, that's what was confusing me. I still have a lot to learn about CAM settings.

Mach 3. The curves i was referring to were tree leaves roughly spade shaped and maye 3/4" long. I think most of the problem was probably that i was not in constant velocity mode

As for 25 IPM...

When routing MDF, i seem to be getting a lot of paper left on the edge that is a pain to clean off.

What speeds/feeds do you recommend for MDF? I have been doing about 25 IPM with0.25 depth of...

Thanks all for your responses. I will definitely try the different things you mentioned. The "constant velocity" setting is what i had in mind, as i figured there was some way to smooth it out, but...

Hello all,

When i cut with my machine, when it does curves, it is very jerky around them because i have each curve broken into linear segments (you can imagine how long this makes the G-code with...
