About to buy an R1

To much tension

Welli overnighted some PTFE tube to guide the PETG better and although I've had about 3 failed prints I think I've finally got it to work on one machine. I think an oiler would really help it though so I'm rigging one up pretty soon on the second printer to see

I'm having some issues with my second printer, here's a pic of my first layer. I've messed with the settings but can't get it to change. Any ideas? The other printer looks good as long as I can keep it feeding.

 

Either under extrusion or your offset is way way too high its hard to tell

I've found with the esun stuff it sometimes snaps so I use the same set up as if I was printing flexy

Well I just finished up a 13 hour print with just a couple snags, stopped feeding once, clumps accumulating random spots, the small lettering I need readable was far from it and most importantly once I pulled it off the base its super warped. It's sticking good to the painters take and glue just not the corners. I didn't even notice until I pulled it off.. I turned up the bed temp and I'll see if that helps.

Once I put an oil on I haven't had a problem with feeding so I'll probably just keep it goin.

Just checked and my Y belt was really loose on the one that's printing funny. I'm going to have to mess with it in the morning tho. Thanks for the suggestions.

 

Pretty ugly.

 

Now I'm wondering if my extruder temp is too high.

I got some of that high dollar mat in today but I need to make the machine auto level before it preheats the extruder. Not even sure I wanna mess with it.

 

I did a smaller block with PETG and recessed lettering and it turned out pretty good. Maybe it's my extruder temp, i was worried about the layers bonding so i turned it up from 235 i think to 245. I tried slowing it down before it did the lettering but that didn't help, this next one that's printing now is even uglier. Would raised lettering be any better? Also looks like raising my bed temp to 85 did nothing to help it from bowing. Maybe i'll try it with the heater off and see what happens.

 

What layer height are you printing

Printing at .3mm, don't really want to go smaller because these are already 13-15hr print times but maybe ill drop it to .2 and see what my times look like and if it helps. Yeah i think one side of this is warped worse than the first one and this lettering is completely filled in and looks like garbage. I'm printing in PETG not PLA but i think i'm going to start my next one without heat and a 235 extruder temp and see what happens. Time to open another new roll lol. How frustrating, starting to wonder if i can even get these to work.


With simplify3d could i specify the lettering spots to have a smaller layer height and to print slower?

 

Starting to wonder if I'm oiling too much and it's causing it to pull up. Also it's the tape that's pulling up and I cannot get it to stick without tape so I'm going to try to wipe it better with alcohol or maybe try to find some better sticking painters tape. Lowes had some outdoor printers take I believe that may work better.

Also, when it prints the first layer some of my holes only print 3/4. Is that my slicer? I'm still using matter control.. until I can get the basics figured out.

 

I'm going to print a few small blocks today and then if all goes well get some better tape and start a big one tonight. Any suggestions on bed temp? Can't figure out what would be best. I don't know how I got my first ones to stick to the bed without tape and not lift up. They were only 20% infill tho.

Just went home for lunch to a print that was sticking good when I left but came up. Started another one without oil and it misfed on the second layer.. One step forward 3 steps back..

 

Got home and my tensioner bracket was snapped in two. Switched it out with my other printer so i can continue with the complete failures... I just realized one of my z axis limit switches was turned around 360 degrees, switched that around and i have a print sticking right now. I adjusted my z height to .85mm which seems low but maybe its because of the z switch being turned, No idea. hopefully this thing doesn't end up at the bottom of my stairs tonight. I have a TON of work i don't want to send out to someone else and i'm supposed to go out of town this weekend.. Thanks again for all the help guys.

 

Ok so as I sit here and watch my prints to make sure its working I'm wondering, do I need to worry about filament getting built up on my nozzle? Is there any way to prevent it if so?
