Found the following info on the gnea/grbl Wiki on github and am confused. " Just make sure that all of your drivers and the Arduino share a...
Thank you.
Found the answer on the, surprise! surprise! electronics/motors forum. love this site.
My information is that stepper motors that are microstepped require 2 times their rated amperage be available as both poles could be energized at...
Short background; have been slowly upgrading a basic Banggood 3018 (limit switches, bigger spindle, stiffer frame etc.) and are upgrading to NEMA...
Thank you. That is exactly what I was looking for, grbl sets the Arduino pins low. Steppers are DM542's.
Getting ready to connect 3 stepper drivers to my Arduino UNO equipped CNC. The UNO is programmed with grbl 1.1. The driver manual asks if the...
Thanks everyone for the comments and assistance, much appreciated.
So I finally found the grbl/wiki for 1.1 that everyone was referring to and had my questions answered. Many thanks for your patience. Any thoughts...
This was the poster on my EE sites logic. Again refers to 9, 10 and11. Were just trying to get this right not cause conflicts.[ATTACH]
These are the images I have of limit switch pin assignment.[ATTACH] [ATTACH] Was told, by Peter, that the old pin assignment applied to V0.8??...
Thanks again Peter, What's your take on the capacitor theory as above??
Thanks for responding. This is kind of my point. That site shows the limit switches on UNO pins 9,10 and 12 which I am told (see my post under...
The Net's glory is also it's curse, there are so many conflicting wiring diagrams, some old some new. Is there a 2020 consensus on the best way to...
We are setting up our own stepper controller using an UNO/grbl combo. Have one drawing of UNO pin layout that shows the limit switches on pins...
Thanks, that was my concern. Will use the standard transformer.
Thanks for responding: Wouldn't that only apply to steppers tied in series?? A single source tied to a distribution bus with the steppers then...
We are building a controller using 3 stepper drivers and an Arduino UNO. Power comes from a 14.5A, Meanwell power supply with 3 outputs. 2 of the...
