Looks like a new replicape/controller board should be launching soon. Can’t wait to see if the big thing is tackled: the price.

Dear G+ friends! It is with fear and joy I announce that the future of 3D printer controller boards launches on Kickstarter on Monday! I’ll be spending the next 30 days sharing whatever news I have about the campaign here, but nudge me if it gets too much : ) Meanwhile enjoy this video of what the beta testers think! #replicape#kickstarter
“Looks like a new replicape/controller board” sounds biased, since the product is literally ‘Replicape’. Don’t get me wrong, I’m here for the latest and greatest info on controllers especially since I’m working on my first delta, it just seemed kind of odd in this group.
@Elias_Bakken It looks like you’re using TMC2100s with no end-user-config breakouts? Or are the config pins controlled via software? Would love some details on how the drivers are set up, since the TMC2100 is still pretty “new” to the community.
@Ryan_Carlyle most of the config pins on the TMC2100 are tri state, so they are controlled by a shift register + some tri state buffers. That gives individual control on microtstepping and a full 8 different variations of decay modes. The schematics are available already: https://bitbucket.org/intelligentagent/replicape (i hope that’s right…)
When will it be available to
Purchase or more beta units? We could do some testing here. Jetguy has a new printer that he is using to test all the printer boards he has to compare the results.
@Jon_Caywood , I said it that way because I wasn’t sure if @Elias_Bakken was electing to name it something else, or if it was just going to be a v2 or whatever.
@Elias_Bakken by the way, thank you for not using 8825s on this rev, they’re really not appropriate for 24v systems paired with low-inductance motors. (Blanking time is too long, chopping frequency is too slow.) I think the Trinamics should work pretty well in spreadcycle mode.
