Another printer (it is a disease, once you start collecting them...)

feel like I'm in the stone age.....no cams watching my prints...just a visual inspection here and there

 

I am lazy (no, lazier, lazier still, yea... about that much).
I ain't walking down there without t reason. (unless I am going to the bar, it is the general area).

 

Are you saying your not always in the bar ? im firmly planted in mine....haha. just walk back in to check the prints

 

No bed in the bar, yet...

It is printing its first DePrime now.
There is no way to adjust the Z offset or any of that. It auto calibrates, updates the EEPROM and that is all you have.

I see no easy way to tweak that.

 

Both great ideas. Will take a few days

We were having a lot of issues with the bowden feed not wanting to ... feed and looked like maybe an extruder jam.

We popped a fuse on the Rambo and (of course) they are special little buggers so -- Thursday I will have replacements.
I also need to recheck the effector (the fancy name for the extruder and mount) since something down there might need more kapton tape to avoid shorting. I was messing around with that when the extruder fuse let go.

The issue with the extruder jamming is because we probably did not have the bowden tube quite far enough into it. Will clear the jam and fix that as well.

 

man that sucks. hopefully they get you squared away quickly. damn learning cuves

 

Yea, I knew it would be a learning curve for the new tech. It is really different.

When we had it printing it would do the autoleveling and tap around the edges of the glass and I was puzzled because... how did it know? When it started printing it would swoop down at high pseed and then slow down close to the glass. There are no limit switches down there. Turns out they have an accellerometer on the effector and that is what is uses to 'know' where it is. Cool.

 

watching them rocket from top to bottom is scary during the home lol . Very awesome.

 

It has limit switches at the top, but ... the firmware has no configuration to set the size, just add longer rods and it will autonagically be bigger. The accel is the bottom limit as well as for the 'edges' of the build plate.

 

Well, I rebuilt it today and eliminated their "thermal protection switch" which complicated an already complicated hotend assembly.
It is much better now electrically, but I wasn't paying attention and may have not left enough threads for the nozzle. It is in, but only with a couple of threads. Fuse doesn't show up until thursday so I may redo it again. Or I may just try it like that and change it if needed this weekend. I went up to a 0.6 nozzle (from the 0.5) however at some point I will convert it to a really big one (like a 0.8) and leave one Robo for fine detail stuff.

 

Working again. Still have some fine tuning to do.
We will see how this turns out, tall vase mode.

 

I tore-down and reassembled the effector (twice more) to get it to where I was happy with it. Removed the thermal switch and replaced the heater core since the wires needed to be longer. It was already a 40w core so that was fine.

 

To prevent the feed/extruder from skipping I droped the feedrate to 87%, but not sure why it is skipping. I will need to research that. I am just not Delta-savvy yet.
