Re: Bleeding Dollars

How does one decide where all their money goes? I am looking at many things where they are taking caliper measurements much finer than my Harbor Freight caliper will go. Do I need to invest in a better one? I see many folks are using Mach 3, CamBam, QCad... Similar to what I was asking in another p...

Re: TinyG Homing & Limit Switches

I followed the guide posted here: https://github.com/synthetos/TinyG/wiki/Homing-and-Limits-Description-and-Operation Most important tips I can give you is to make sure the unused limit switches are turned off in the configuration, and to use NC configuration for less noise. You do not want noise to...

Re: Question about power supply.

No you wouldn't damage it, but your stepper motors will get hotter and have less torque.

Sounds backwards about the heat, but thats what I read somewhere on this forum or other CNC forums.
You'd get optimal torque when supplying a motor with its rated Ampere per winding.

Re: digitizer probe on grbl

I think you need to use MACH3 for probing right now.

Seems like GRBL will support probing in the future, as you can read here: https://github.com/grbl/grbl/issues/140

Re: NEMA 23 motors needed?

Power management is turned off on X and Y, so they stay powered all the time. Cooling with copper heatsinks on all drivers, and a powerful 90mm fan blowing on the heatsinks and the underside of the TinyG. I had the same experience as you, the dremel would drift in the Y direction while it should hav...

Re: "OEM" Trim Router 1.2kW

I hope I'm not too late, but I had the same problem when I tried to find a good router/spindle from my machine in Norway. Ultimately I bought a Kress 1050 FME-1 from Germany, and I'm very glad I did! 1050W - electronic speed control from 5000-25000 rpm. It's super powerful, but also no runout at all...

Re: Random thought: double Y rail - Possible?

I think you'd have lots of problems with binding (is that the word?) and gantry racking. It's tricky already trying to square it with only one rail, but if you double it, I imagine it would be even more sensitive to twisting across the X axis. I would go with bearings and linear shafts instead like ...

Re: NEMA 23 motors needed?

You're right. I shouldn't have to depend one this one controller so much, as it still is a beta product.

Re: NEMA 23 motors needed?

I shortened the values to 2 decimals, and the max line length in my G-code was under 50 characters at most.

Still the same missed steps though :(
