There will be many who use these and state there is no problem. https://www.banggood.com/Machifit-Wireless-Electronic-CNC-Handwheel-MACH3-6-Axis-Pulse-Pendant-MPG-for-CNC-Engraving-Machine-p-1365963.html OTOH, I have one of these because I don't trust wireless for running the machine. https://www.aliexpress.com/i/32844453793.html I don't even trust myself running the machine as a gouge in the vise will attest. But there was support for it and it works reasonably well. http://linuxcnc.org/docs/html/man/man1/xhc-hb04.1.html Again with the dual boot PC and either MACH3 or LinuxCNC.
