I had the issue with G53 G0 Z0, and it dragged a carbide bit across a hardened vice jaw... When you create an NC program (8:07) there's an option on the right for Safe Retracts and Home Positioning. I there you can set Safe Retracts to Clearance Height, instead of G53.
@@BMRStudio I've got two theories as to why this happened to us: 1. We've got our Z axis the wrong way up (in software) and positive Z should be downwards - If you look at 3:04 in your video the Blue arrow is up, should that be down? (Mine points up too) - you'll need to invert the axis in UCCNC as well. This is only the problem if it's causing the G53 to go the wrong way, which I'm kinda sceptical of, TBH. 2. I think this is the more likely one. No homing. The machine doesn't know where Z0 is, as G53 is based on machine coordinates, if they're not set by homing it'll head off in some random direction. I've since added home/limit switches to my machine, so I should be able to test if that's the case.
@@matthewgreen8454 Nah :) Tomorrow You will see what caused the travel down.... Its just..... Wrong default settings in the default UCCNC installation. Not the switches, nor the setup, neither Me. Just one stupid data in a small box....
I make mistakes too.. So what You see, is not only the controller, software, computer, protocol, postprocessor, material, clamping, cutting speeds, cutting tool, working heights, currents, voltages, distances, tolerances, materials, dust collection, metrology, science, applied programming language, wearing, temperature... may I stop here.. meh... But human skills too :)
Well, the G53 G0 Z0 should be at the top of your Z axis. So the G code will tell the machine to go max up to the Z0 start to move to the position and go down into the material. So either you turn the blue arrow in Fusion so that Z+ is going to be down instead of up. But that can be a bit dangerous and you might destroy some endmills. I use the free version of Fusiong too and it is working perfectly, yes you cannot use different tools in the same postprocess, but that is ok for me. So you need to change position of your Z axis sensor so that the machine is having G53 Z0 in the top instead.
Its already set Z Home switch to DIR Positive. then I have an extra offset. I did find a way to modify the postprocessor and get rid of this line. This should be GO TO WORK ZERO PLUS Safe Z!! Not Machine Zero. Its just stupid.... So, Probably I have a issue around G53, G54 G55 G56 G57 G58 registers. Another video. Let You guys laugh on me and on Fusion

Thx! You are genius!
I find an another solution, but in the next video I will show Yours too!
I don’t understand why this isn’t a DEFAULT option…

Oh wow that looks so complicated. I thought 3d printers are difficult to use but wow

I can set my sleep timer on the pendant to what you can set it to in the plugin, if I set 40 seconds it will go into sleepmode after 40 seconds.
Whatever I set, no change.
I have to do a customer claim 🤪

@@BMRStudio But when you home Z is it going up or down from the machine board ?
@@NiclasGudmundsson up
@@NiclasGudmundsson I never seen any CAD program calling MACHINE ZERO on the beginning of the job. Never. Nowhere. Just stupid
@@BMRStudiobut then I think you have something else that is wrong. So if you move Z down you are getting negative values (machine cordinates)?
