I have finished building my RAMPS+ board, apart from the last few Pololu Stepper carriers as they are still out of stock in the UK. :(
But by 18th march they should start to ship out more Pololu steppers to people, so hopefully I can test it fully around then.
And while I waited for those I have just finished my first Bowden Extruder with a 1.75mm filament drive and my own design of a push-fit style hot-end, photo's and more on that tomorrow.
Rich.
i like your board, though i was wondering why the bigger pololu drivers on the side there.?
ReplyDeletei do like the conectors your using for your steppers though.
Hi,
ReplyDeleteI plan to use the extra two Pololu steppers to drive extruders, so the PCB is designed to be cut so these can be placed closer to the extruder. So I selected the Pololu stepper carriers with the on-board Voltage regulators for this purpose, then you only need to run the +12V to the extruder. I hope this should give me reduced electrical noise doing it this way.
Yes I really like these connectors, they do work fine without the screws, but it's nice to know that are not going to vibrate loose.
