How's your Y belt loose? Do you have much woobling?

[legarasta]

i built this printer from scratch and it's quite big; they are not "loose" but aren't very "tighted" since i don't know if it's good to have lots of tension. As for this print, it was printing at 70mm/s, wich is faster than i usualy use (40/60 mm/s); but then, i'm printing for two weeks only, i'm very new to all of this.

Maybe those inperfections come from there?

About woobling, yes, at this speed it was woobling a bit. I was trying to print this part to replace the CNC machine alluminium part to try to get the moving mass weight down.. :/

[bolsoncerrado]

I definetly started to get better prints once I removed all wobblings from the bed AND the whole X/Z axis too (ie anywhere where a LMU bearing was present).

The global issue with LMUs in a careless factory is that when they're placed in the rods, any missalignment will make the small bearings inside come loose and ANY bearing missing will make the rods wobble afterwards.

So you can bet that in Rapide's case, and its total lack of QC on their factory, this has, is and will be an issue forever.

Thank you SO much for this post. 18 hours into a print I tripped over the USB cord and unplugged my printer to my dismay but this post gave me the basics which allowed me to figure out how to recover my print.

Here is where it crashed

Here is where it's at now

Well, congrats, but thats that blue painters thing for?

I've been able to resume further prints without the need to add any additives to the layer.... just leave the first "additional" layer iwth the fan off then turn it on on the next layer.

Hey guys, great guide btw!
Only problem i am having is i lost my power and the print head got bumped so i cannot get to the exact same home position. I have been setting my home manually.

Any suggestions?

[smellycat]

To reset my home position after a power outage, I
- manually raised the Z to a safe position
- homed the X and Y axes
- unplugged the X and Y steppers,
- moved the nozzle to a safe place as close as possible to my normal homing location
- auto-homed the Z-axis
- raised (Z) to a safe location via the controls
- plugged in the X and Y steppers
- auto homed X and Y
- used the controls to move the nozzle to the correct starting location (using the friction on a sheet of paper for the height)
- determined the correct Z-height via M114 or the control screen (plugging in the board to USB at this point caused a reset, and I had to redo everything)
- resumed the print from there as above...

Now to see if it was successful!

Pardon for the post derailure... what brand and type of filament specifically is this white material?
