Yay! A successful weekend! I have the Primo assembled and squared up, tensioned, etc. All that is left is a lead screw (arriving today) and the electronics! I have an old Uno based board I could use with GRBL, but I’d prefer something newer runs Marlin. Thinking either SKR Turbo or mini Rambo. The $$ difference is ~25%, but the question of reliability and support seems to have me doubting saving a few bucks (and getting a bigger screen and wifi).
Here’s some eye candy:
You’re going to wish you had installed the steppers on the trucks before putting them on the pipes. Those little screws are a PITA to get into the stepper when upside down.
I removed 2 of mine after building the machine and felt like a contortionist trying to see where the little screw head was to get the screw driver on it.
I agree… I did just that, but then couldn’t feed the belts through, so I had to remove the motors and the idlers to get the belts in. I’d say thread the belts through and install the motors before you mount them on the rails.
It’s coming together! Feels like it’s getting really real now. Got my V1 order coming in this afternoon, as well as an amazon order with some cool switches I’ll be using as a “control board” type thing. Also planning on making my build thread once those packages come in. In theory I should have all, or at least most parts printed by this weekend so I can get started building (52.7% of parts printed).
When I installed my belts I had already had the trucks mounted and the idlers and motors in place. I just fed the belt through the truck flat, then pushed the belt in with both hands on either side and the belt looped out between the idlers.
