Getting components for my new build and $40 for a touch screen that I might not use often seems steep…
Can I reuse my ender 3 TFT screen? I know functionality might be limiting but I plan to mostly control the CNC through CNC.js.
Well I think it kinda depends a lot of ppl don’t want their PC in the shop getting all dusty etc.
You could always add it later if you feel you need it.
I already have a PC in my shop, but am loving the cncjs from v1pi to run my burly mpcnc. You could easily use a tablet via wifi and not need to worry about dust in fans, etc.
V1 sells the SKR Pro 1.2 with a touch screen. Lots of people like the touch screen, but it has been a source of problems as well. The are many machines that run with no screen, or a 12864 display. If you are going to be running Marlin (most MPCNC users use Marlin), and your board supports one, I think a 12864 display is a good investment. It allows you to run files without a computer or depending on a wireless connection, and it is good for troubleshooting certain problems. They typically cost around $15.
If you decide to not have a display, I recommend enabling the Emergency Command Parser in configuration_adv.h. Without having it enabled, your job will hang if there is ever an M0 (pause/message) g-code in the file.
If you decide you want a touch display, consider getting the same display that V1 sells with the SKR Pro (TFT35 E3 V3). V1 has made substantial changes in the TFT firmware to support MPCNCs, so if you buy this exact display, you can use V1 maintained firmware. If you go with another display, and if any of the 3D printing features get in the way, you will be on your own in addressing the isssues.
