Re: ePC hold-down method

My biggest problem with PEI is that large parts pull it off the plate and then you get air pockets under it that won't come out. If the air pockets are near the sides or run all the way to the edge then you can push the air out the edge, but an island of air trapped in the middle is virtually imposs...

Re: Fan connections... variable speed fan not working

Dang, I wouldn't have thought these el-cheapo fans would have all that going on inside. I'm going to hack the next one that fails apart and see if it has all that tech. I have a couple bed fans that just won't run for whatever reason. I'm printing the same gcode file on 9 machines and the fan won't ...

Re: Worn out extruder gear?

I've done what you guys are talking about but have lost too many prints by not being there when it runs out. I run these things day and night and sometimes it's hard to tell if there is enough to get through the night. Even when you are in the room it just wastes a lot of time having to keep an eye ...

Re: Fan connections... variable speed fan not working

PWM is a pretty common way to control speed on DC motors and should be very responsive to different pulse widths on any DC motor. If it is not working then I would suspect the software isn't implementing it correctly.

Re: Worn out extruder gear?

I'm just running out of places to put these things. I can't use them with the amount remaining because there is not enough to do even one of the large parts I'm making. I noticed PLA gets brittle after about a week in open air too. Not sure if it is just the first layer of filament or if it gets int...

Re: Extruder Cooling Fan Won't Run

Doh! Only after taking everything apart and bench testing the cable do I figure out that the extruder fan is Fan1 and not Fan0. I was thinking each connector on the extruder junction box had a unique connector on it that prevented you from plugging things into the wrong spot, but I guess the two fan...

Re: Extruder Cooling Fan Won't Run

The extruder still works, so that rules out a blown fuse on the rambo. My guess is broken wire in the cable, but if it is a blown fet or something on the board I'm just going to wire the damn thing direct to power rather than buy a new board. It's not worth shelling out $180 x 2 to have a fan that t...

Extruder Cooling Fan Won't Run

My extruder cooling fan just stopped working on one printer, then the same thing happened on another printer. I disconnected the fans and plugged them into a working printer and they ran as expected, so it is not the fans that are bad. Before I get out the multimeter and start poking around I was wo...

Re: ePC hold-down method

I got it to stick using a 4 line brim on a 100c plate which was scuffed with 320 sandpaper. My printer just aborted the print half way through though, which I've only ever seen happen from the extruder hitting the max temp. I wish simplify 3D would store a log of the commands instead of letting the ...

Re: ePC hold-down method

This is a harder material to work with in my opinion. Hairspray and a 110* bed is what I have run. Can't comment on PEI, I can't get anything to stick to PEI. I print on MIC 6 only. Have you tried lower bed temps? I couldn't tell any difference between 70 and 100, but waiting for the bed to reach 1...
