I have a Hictop printer with some issues so I'm gathering parts to update it. Among them is a Big Tree Tech SKR 1.4 board (not the Turbo, which is identical except runs the CPU 10Mhz faster).
Do you have any experience with that one? There are a ton of display boards for BTT controllers but what I haven't been able to find is a list of what's compatible with which. Stepper drivers shouldn't be a issue since it looks like it takes normal StepStick / Pololu modules. I see someone did get around to making the bleedin obvious accessory, the StepStick breakout to screw terminals. https://forum.makerforums.info/t/ariel-yahni-here-is-a-better-picture-of-the-stepstick-breakout-board/7272 That would enable driving big motors with high power external drivers.

I am currently rebuilding an Ender5+ using the new stepper/servo drives from hanpose, that are rated for up to 90 volts for the nema 17 motors used on most printers. Most of the big tree tech controller boards use 1.5 micro-sec step pulses, but I am finding I need to stretch that to 2 micro-secs if I don't want an occasional miss, this while driving the lc42 driver. These drivers all have opto inputs, and need a little longer step on the less than 5 volt signals. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
