No need, atleast I've found none. It's in a precision collet and repeatability is plenty good for hobby use. Had no issues finding the correct coordinates even after failing a job and restarting it by probing again against the same stock point.

@@crabsshed thanks for responding. About to install a drewtronics touch probe on my machine.

Hi, its a custom design and build, loosely based on printNC CNC (mainly the steel gantry). Machined all aluminum parts myself on an older CNC Router (Upgraded WorkBee). Nothing special about it. 1610 ballscrews on XY, 1605 on Z, HGR20 linear rails from China, 180W servo on Z, 400W AC servos on XY, all from JMC China. Spinlde from China, 2,2kW HQD, aircooled but modified with high flow fan to be independent from spindle speed. Controller is from CNCDrive, UC300ETH + dual port breakout board.

@@crabsshed thank you very much for the quick reply😉

Thanks, I am glad it inspired you. As for your question, for XY probing I always used a precision turned rod of known diameter so that the measurement would be accurate. Endmill just for Z axis probing. That was then. Now I am using. A 3d touch probe, nothing fancy, just a cheap one from aliexpress, but it makes things even simpler, more precise and can probe any materials, not just conductive ones.

One I designed and built myself 😉. Nothing commercially available. Slightly inspired by the printNC cnc (steel gantry).

Is the machine for sale?🙂

@@peterzakutansky1418 no, only one piece exists and I need it 😉

Custom designed and built by myself.

Non, je ne le fais pas. Vous devez créer un gcode compatible avec votre propre machine CNC.

Merci ;) @@crabsshed

It is doable. Not very user friendly and there are much better options in this regard but certainly doable. Been running with them quite a long time and personally I am happy with them especially considering the price at the time of purvhase. Nowadays there are more reasonably priced options like original Delta servos for example (with proper autotuning).

Nothing, just happy that the cnc conversion is working OK.

Yes, it's PVC. Good enough for simple tests for now. Still lot of work finishing electrical installation and figuring out the software side. For now I am just happy it works.

Sorry, not sure what you mean by that.

More or less. Had it in the company for years. Been planning to do cnc conversion since evre... Finally made some progress. Basic stuff should be working in a few weeks hopefully 😅

Best chip evacuation IMHO, 2 flute works great too with a larger diameter tool. Small tool with lot of flutes is easy to clog.

Yes, in the past couple weeks Ive been experimenting with carving custom xmas tree ornaments in poly, and its just been a mess with the bits I have. Guess I get to order more parts now... Yay! @@crabsshed

Single flute for most plastics and aluminum at high rpm. The chip evacuation and chip loading allows you to cut without melting, plus it aids in evacuation. Most of them are polished as well.

No, all are still working fine.

@@crabsshed Excellent

No idea. I don't use Mach. Perhaps it has some probing menu like uccnc where you choose what you want to probe.

It's Uccnc software (and hardware) not Mach3

Bottom of gantry to spoil board is 180 mm. Z axis travel is about 210 mm.

This was actually a upgraded Workbee CNC with leadscrews on Y and Z and 1610 ballscrew on X axis. Nothing fancy, standard Chinese ballscrew.

No idea. I don't use it.

No idea, but I assume it would work yes. Never used mach3 personally.

Sorry no idea what you mean.

Hi, Z axis uses a 180W JMC servo, but has a lower pitch ballscrew (5mm vs 10mm used on X and Y) and also has a 2:1 belt reduction. Speed is limited to about 7500 mm/min but I find it plenty enough for Z axis. Acceleration is set to about 0.4g and works fine. Not sure it could do more and I did not try it to be honest. Weight of the moving part including spindle is about 25kg like yours. Maybe adding some gas spring or counter ballance would help too so it does not have to work too hard when moving up. The belt reduction and low pitch screw help hold it in place. If you went with direct drive then you'd better get a servo with electronic brake so it does not fall down when power is cut. JMC (and other manufactures) has all versions of servos available with a brake too.

Hi, welcome :). At start I did tune them one by one. Every time a little for one side then adjust the other side and so on. Later I wired up one servo via USB and the other one via RS458 and was able to open the tuning software twice so I could tune them both at the same time. But in general same procedure, just saved a lot of time as I did not have to change the USB from one side to the other.

Hi, it is just a cheap nozzle from Aliexpres. Search for CNC mister or something like that and it will give you many options.

En realidad no está ardiendo. Solo en los pases de ranura completa se calienta. Las trayectoria adaptativa están perfectamente bien y la misma herramienta logró producir muchas más piezas.

Thanks Chris. The second pass was to make nicer side finish (not sure if necessary but it looks great) . Otherwise it can manage 8mm PVC or acrylic in one go without any problems. Didn't have any thicker stock to try.

Not sure, did not measure it but it didn't glow or anything like that. And it did survive OK and did a bunch of more cuts without any issues.

@@crabsshed Nice, guess I need to try bumping up the rpm on my machine as well.

No need really. It was intended mainly to test hole patterns and rough shape. Final piece was done properly from aluminum later.

Everthing is in the video description ;)

Yes, grblHAL is much more capable than 8bit grbl and I do recommend it. I do not use it anymore as I changed to UCCNC software and hardware. While I was using it it was performing very good and I was happy with it. The guys at printNC CNC are focusing on grblHAL along with some updated hardware flexiHAL so it might be worth to check in their Discord channel for more info.
