Unanswered 3D Printing Newbie

If you are targeting a temperature higher than the maximums allowed by the firmware that will happen. The bed is limited to 85 and the extruder to 245 I think. So in practical terms you can really only set these to like 83 and 243 respectively as they will overshoot and trigger that shutdown.

 

Can anyone tell me what this is for? When first set up the printer, it was loose, and I tightened it before I ever printed anything, but I don't know what direction it should be facing, it spins when loose. Also, when I rub my fingers down the threaded Z-rod I can feel "pits" in the threads, in a couple places on each one. As if the threads are worn down in those places... just one full thread in each location, not an entire section or anything...

 

Ok thats what happened then, I put the bed at 90C. Ive been reading How-to's, and I've seen multiple articles that say ABS is good with a bed temp between 80-110 so I thought 90 would be ok to try. Thanks

 

That part holds the ribbon cable for the bed.

 

Is there a certain type of lubricant used on the rods? the smooth Z-rods feel dry.

 

This is beginning to drive me nuts... Ever since that magnet came off and I re-glued it back on, now nothing will stick to the bed. Im not sure if the bed is just not level or the nozzle is too far away...Ive tried re-calibrating the auto level 4-5 times and every time, the first layer doesn't want to stick. The nozzle seems to be too far away from the bed right before it begins laying the first layer down. Ive messed with the M565 Z-# from -1.0 to -.3 and nothing helps.

 

Sil glyde is also a good lubricant, it is rubber / plastic safe.

Are you doing the three point Matter Control level procedure? If so, stop. Does the nozzle make contact with the bed in all nine locations when it goes to autolevel?

 

Yea I've been using the 3 point level system, i thought that was required in order to get it calibrated for the auto level. So what makes it auto level without the 3 point calibration with the sheet of paper? Do I need to un-check a box somewhere? And yes the 9 points appear to all be touching, but when it starts laying filament, it raises the nozzle to approx. 1/8" off the bed, so the material just goes everywhere and turns into a big blob...

 

Hmm, i don't see a setting that "says" z-offset... this is all i could find. of course this is the matter control cura engine. i downloaded the cura software from their site, but it was much different, and i wasn't sure i should swap.

 

Somewhere in mattercontrol there used to be a box that said "enable software auto leveling". Uncheck that. As someone once put, it is like wearing a hat on top of a hat.

Somewhere under the advanced settings is where you can change the Z-offset. I have not used mattercontrol in several months. The regulars around here are not a fan of it.

 

General
Size and Coordinates

Z Offset: This value will be added to all of the z positions of the created gcode.

This is where the z offset is located. I think by default it is 1 (not positive on that though). Most likely you will want to go to .8 or something along those lines. You can go as small as .01 increments if you would like. If I were using Mattercontrol mine currently would be .61

 

I had been messing around with that number since the first guy told me about it in my original posting. For the last several prints its been at z-0.4 thats lower than what everyone has suggested, so I'm afraid to go much lower. but its still raised off the bed about 1/8 like i mentioned before...


EDIT: Ok right after i posted this, the next print i did, magically closed the gap and stuck to the bed... i have no clue what happened, maybe it had to do with un-checking that "hardware leveling" box...now I'm back to trying to get the quality of the print better

 

Step 1 is to disable the software auto-level and return your z offset to -1 and go from there. You need to let the firmware do its thing and not compete with the software.

If you are ready to give up on Matter Control, go here.

I've seen it come up a lot where people are intimidated to setup new software such as cura. To...

 

I would just go the Cura route to be honest. Mattercontrol is horrible for lots of reasons. If you need help setting it up you can go to the shoutbox and we can help you right away. Someone is almost always on that will be able to walk you through it.
