CTC i3 pro B to threaded rods frame

I'm thinking about converting frame to threaded rods frame like reprap mendel.
Ive have found this thing https://www.thingiverse.com/thing:2728742

Is there something similar, already done/tested like this thing above?

3D touch sensor installation and configuration

by Jaymboii

I have a CTC prusa i3 pro B, It has a GT2560 rev A board. I've downloaded the latest version of marlin (1.9) and done the necessary changes to enable the sensor.

Gcode to deploy and retract the pin works, as does the self test, however, when I attempt to home the Z axis, without fail every time, the nozzle crashes into the bed and the probe doesn't deploy at any point

When I send M119 when the pin is triggered, I'm intermittently getting open/triggered signals. I'll send the code 10 or so times and get open, then randomly get a triggered signal, even though it should be triggered all the time..

If anyone has any ideas as to what may be the problem id be really grateful for the help, i've been at this for 3 days and no results so far.

Have you got Y axis issue?

by Alex_Y

Just have had an issue with print quality where Y axis layer's rear end surface was shifted sometimes by 1/4 mm, front surface fine. Supposed loose belt, tightened it and result was much worse. When removed belt to inspect it if something was caught and started blocking it I've realized bed carriage is running like old rusty bearing. With belt on I've though it is just stepper. Added drop of silicone sewing machine oil per balls row (4 per bearing) and realigned them. It was preassembled in kit so never touched it but apparently should.
By the way Y belt fitting to carriage is way too high, will have to print new fitting.
So if you have print quality issues check bearings.
