Convert UP Plus2 auto bed leveling sensor to filament sensor

I'm using octoprint for a while to print with my UP Plus2 since I replaced the CPU.. and with octoprint I can easily manipulate print with plugins. One of the plugins is "pause when filament runs out" and the sensor attaches directly to orangepi/raspberypi gpio.. For this purpose I converted the aut...

Re: Custom MCU-module for UP! Mini...

also as you can see on the pic, you can attach Zprobe switch directly on the head, no need to drag the cable all the way down from the banana jack. just short the zprobe to gnd :D

Re: Custom MCU-module for UP! Mini...

What tricked me was the positive connection goes to the omron relay before going to the junction of Ra22 and Ra20. yes, for some reason the temperature input is disconnected via relay when the enable for the motors is disabled. weird concept but.. what's weirder is that machine loses USB connection...

Re: Horizontal resolution of UP Plus 2

M92 X644.00000 Y644.00000 Z644.00000

so you have 644 steps per millimeter for all three axes. in theory the resolution is 1/644mm = 0.00155 mm

USB disconnect on "disable motors"

Not sure why but "almost" every time (19 times out of 20) after the motors are given command to go offline (the stepper driver EN pin disabled) the USB connection is lost. Is this some bad EMI on the board or some other reason (like enable driving something else on board, I see that motor driver EN ...

Re: Custom MCU-module for UP! Mini...

here I circled the track that is input for PT100 sensor, check where it is on the connector, just use a simple ohm meter to find where on the connector those two are

Re: UP Studio vs Simplify3D

I love my Up MIni but one thing I hate about it is the fact that it isn't open sourced! Please, please let us use your products with third part apps such as Simplify3D! simpllify3d has huge issues itself .. so a wrong project to look at in this content since it's also closed and not expandable/exte...

Re: Carbon fiber material for UP+

you can use any 1.75mm filament filed with carbon or metal (brass and alu avaialable) with UP since you have temp controller .. only your original nozzle will go to hell after half a spool as those are abrasive .. you need to get a steel nozzle or a coated nozzle. you can get one from microswiss .. ...
