At MRRF 2018 there was simply way too much to take in in just two days - here are my favorite bits that you may have missed!

Build the MPCNC you won’t regret it! It’s amazingly accurate.

@Dan_Baldwin this I can agree on

The MPCNC is on my list also. I almost bought his display model but someone else had just beat me to it.

This is what MPCNC could domissing/deleted image from Google+

@Benjamin_Deiss Nice. I did those back in the day. I have our old LP6000 PCB Mill at home and debated converting it into something else.

Hi Tom,
I have an urgent question for you or anyone else in the community. I was calibrating my extruder today and noticed that at regular intervals, no filament was being pulled into the hotend when I set it to extrude 100mm. Since it was so regular, I imagined that it must be that some of the teeth on the gear on the extruder are faulty somehow. I’ve had my printer, the Anet A8, for about four months and have been printing on the weekends, so it hasn’t seen that much use. I’ve been very careful with it and haven’t noticed any other problems with the extruder until this one. I haven’t opened it up to assess the gear yet because it’s late here and I’m pretty tired, but does that explanation make sense for what I am observing? If so, how do I fix it?
I’ll make sure I update my situation when I investigate further tomorrow. Thanks!

@Broken_Prop the extruder gears get clogged up on Boden extruder if you are feeding filament to quick or don’t have the hotend at a high enough temp for that type of filament. I have some PLAs that want 110+to feed correctly.

@Chip_Estrada are you talking 110 % feed rate? Agree on the temp setting , my experience is pla at no less than 195 usually set at 200. I just had to scrape and clean the extruder gear for the first time after going through 4 rolls of filament.

10

Soooo… The extruder gears are not clogged and everything looks pretty clean. I was printing at a higher speed, so I think it might have just been that the hotend wasn’t able to heat up the plastic fast enough. I’ll try that next

11

Problem solved! It was the temperature. I was printing faster without raising the temperature and that caused the extruder gear to get clogged. Afterwards, it wasn’t biting into the filament when I was testing the calibration. Re-calibrated and printed a calicat with no problems. Thanks for the help!

@Dan_Baldwin No, Some of my PLA requires 110 Celsius temp and I set my feed rate to 98%

@Chip_Estrada understood :+1:
