Uuuh... mind... blown... I would love an explanation for how it becomes more rigid. You might just have caused a redesign on my side. Can’t...
Grbl has a max pulse rate that can limit the max speed. I’m guessing you are using 1/16 microsteps? If you drop to 1/8 you might be able to go faster.
This does look very slick! The red is awesome. Could you show more of your Z-axis?
For smaller end-mills the weaker machines should begin to catch up to bigger ones since the weakest point will be the end-mill. So with a 1/8...
2 mm optimal load? Whoa, now I see why you need a more rigid machine. I ran 1/4" at about 15000 and the 1/8" at 25000. I think the Makita has...
So far I've pushed the machine to do 1/4" 2 flute, 6mm DOC, 0.5mm stepover ("optimal load" in F360) at 2800 mm/min. 1/8" 2 flute, 6mm DOC, 0.5mm...
I tried drilling with the 1/8th drills and the flex was about the same as the other approaches (which I expected). The finished hole also seemed...
First a caveat, I'm a computer guy, not a mechanics guy so take anything I have with a grain/pinch/mound of salt. With my machine that is...
Hi So far I have limited my aluminum milling to very exposed profiles (basically shaving of some material on the outside of the stock) and small...
Could it be that the current is too low and it’s losing steps simply because it doesn’t have enough torque? You could try generating some g-code...
My slipping was between the lead screw and the clamping part of the pinion (using the belt reduction coupler). Not between the AB-nut and the screw.
I’ve had similar issues twice. The first time it was a problem that the pinion was slipping on the lead screw and it wasn’t retracting enough....
Looks nice! What pitch are you planning for the screws? I’ve been looking at 16mm screws but I’m a bit concerned with the 5mm pitch type. Do you...
I tested using my 120 deg spot drill and to plunge a 2mm pocket. Both resulted in significant deflection in Z. I also tried plunge with very low...
I’ll report back once I have had some time to experiment.
I ordered some now. I’ll give them a try and see how it works out. I’m concerned that all drilling might prove to deflect my Z too much.
I tried the helical cutting but to me it seems like 1/16 is just too delicate to handle this on my machine. While I’m not thrilled about...
I need to create a 3.3mm hole for tapping. My initial idea was to use a carbide spot drill to create a dimple and finish it on the drill press....
Tension just feels like a superior construction. But I suspect that you are correct. 8mm really doesn’t feel all that confidence inspiring at...
My concern isn’t backlash but rather whipping/bowing of the lead screw. Especially for 1m screws. Constraining it from this should make movement...
