Mine didnt bind at the drive gear, it bound up right when it entered the top of the filament drive. The thick portion was about an inch or so above the ground out section

Ok so I ran the bit through and cleaned up the hole a bit. I decided to heat up the hot end and try manually pushing the filliment through it and found that it flowed the best at 270c however s3d won't let me print over 259 or 260 can't remember. Is there any way to disable this? I know the extruder is rated to 300c so I'm in the safe zone just don't know how to tell the computer that.

when you say that s3d wont let you print over that, what do you mean?

If you're getting a MAXTEMP error, thats not an s3d issue

That is exactly the error I am getting.
The strange thing is if I set the temp past 250 it won't start the print however if I set it at 250 then turn the temp up from the control panel after the print starts then it works fine. Any idea why this is?

its coming up on your LCD, correct?

Thats a firmware setting. you'll have to download the arduino software and your m2's specific firmware and edit the setting, then reflash your printer.

It sounds like what you have going on is poorly tuned pid values. Default maxtemp is 270 in the firmware. If your pid is not tuned well and you set to 250 but that inital ramp up in heat over shoots to 270 it will error out. If this is the case then you need to run the pid auto tune sequence. If not and 250 is actually where your maxtemp is set then we were just discussing that in a other thread here

There is an m code for it so you dont have to flash the firmware

Have you tried the M143 to change the max temp setting? I tried it last night and it did not work for me, still hit the max temp at 270 and shuts the extruder off. Just wondering if anyone else tried it yet with any success.

Thanks,
Dave

Note all the red "No"s in the support table. Unsupported. You'll have to edit the firmware.

Thanks for clearing that up. I might reference this link in the "max temp" discussion topic so others don't have the same problem I had.
