Step stick format? #4

Do you have any plans to make a step stick format of the board?

of course only a single chip can fit on the board

just a thought, been using google to see if it has been done and your board is what comes close

no way to place tmc2660 in step stick format. Maybe vertically. Panucatt made"Bigfoot" https://www.panucatt.com/azteeg_X5_GT_reprap_3d_printer_controller_p/ax5gt.htm

bigfoot is not a stepper driver

all their stepper drivers are here: http://www.panucatt.com/category_s/1832.htm

sadly no 2660

Yes, it is. "The BSD109A is a bi-polar stepper driver board using the new Bigfoot profile which is twice the size of the regular pololu style drivers used in 3D printers and CNCs. The BSD109A is controlled using Step and Direction signals from a micro controller. " http://www.panucatt.com/product_p/bsd109a.htm

you can chose them here (3pc Bigfoot 2660 SPI , add $36) https://www.panucatt.com/azteeg_X5_GT_reprap_3d_printer_controller_p/ax5gt.htm

Is there an error in the board on the j400 element? both pins are connected together

hzeller commented 6 years ago

It is intentional, this is a jumper, usually to be just bridged with a 0 ohm resistor; For symmetry, it is on all four parts of the circuit, but usually the last in the chain needs to be bridged. To avoid having to do that, it is connected already by default.

(You only need jumpers if you do not want to populate all chips)
