Lulzbot AO 101 and Simplify3d

by Leftyhokum

Just wanted to throw a thread here that made it apparent using the Simplifi3d - LulzbotTaz 3 settings for older model Lulzbot printers works well. The only things I had to do was set the platform dimension to the smaller size of the AO 101 and add a script to make sure the fan is running. I had been messing with these settings for awhile and finally broke down and bought Simplify3d. Man am glad I did because even though this is an old ass machine it works like a dream.

Printer acting weird

by superryan14

For the past month or so my printer has been running fine. But a problem I had about 2 or 3 months ago started happening again. My Z axis on my ramps 1.4 AM8 started making a shaking/grinding noise and one side of the axis skips around a bit and lags behind the other stepper motor I have a video of it on youtube here


It will randomly get back to normal movement but then the Z axis is uneven.

I'm not sure if it means my stepper motor is dying or maybe the stepper driver but i'm not too sure what it means. any help would be great.

Odd temp errors

by Magic-Goat

So I’m running a good old ramps 1.4 setup and it has worked great until now. It has randomly started stopping mid-print and showing a temp error on either the bed or the hot end. The odd part is that the hotter i have the bed the more likely it is to show the fault 50c and i can usually print for 30-60 mins, 65c and it won’t get past the first layer. If i do not use the heated bed no problem shows at all. Also, if i do not start a print and just leave the printer heating up i never get an error, it’s only once it starts the print.

Error messages that show up:
Error:MINTEMP triggered, system stopped! Heater_ID: bed
Error:MAXTEMP triggered, system stopped! Heater_ID: bed
Error:MINTEMP triggered, system stopped! Heater_ID: 0
Error:MAXTEMP triggered, system stopped! Heater_ID: 0

Again, it seems totally random which error will appear and none of them appear if i do not use the heated bed. All temperatures appear accurate and stable when it stops. I tried swapping the thermistor in the hot end and the errors stayed. I checked all the connectors are secure, wiggled every wire and still nothing.

I thought that maybe the data lines are getting a interference next to eachother so i separated the thermistor bed wires away from the hot end wires but it made no difference.

Anyone seen anything like this before? Any help is greatly appreciated.

For some reason Marlin 1.1.0 wasn't showing the temp drops that would cause the fault. Updated to 1.1.5 and set PID settings for hot end and bed and now works fine. Worth noting that my heated bed is 5mm Aluminum so the PID settings are necessary.
