PID was run at 200

Hotend cannot get to 240

I have a V2, just upgraded to the standard 12V power supply from the old ATX psu but I'm still having issues with heating. I ran the PID tuning and when I tried to preheat to 240, the temperature stopped climbing around 228 and I got the decoupled error message.

Re: Print quality issue

I'm thinking the retraction distance is too high period. The HE280 (Given you're a new poster with new issues, I'm assuming a V3), is based off the E3D Geometry to an extent, and any retractions above 2mm are potentially problematic with both. Additionally, the extrusion multiplier should always be...

Print quality issue

The calibration cube printed great, no blobs or gaps/holes. The extrusion multiplier came out to .86. Next I printed the fan shroud but I didn't get anywhere close to the same print quality as the calibration cube. Here's my settings for ABS using MatterControl Hotend: 225C Bed (enclosed) :95C Speed...

Re: Garbled text on LCD screen

Is there a permanent solution to this? I'm getting this everytime I turn on my V2 and only way to clear it up is to disconnect and reconnect in MatterControl.

Re: Fuse keeps blowing

If you connect the wires together that will create a dead short and surely blow a fuse. You are connecting a positive to a negative, a real no-no and if the fuse wasn't there for protection the wires would burn and possibly cause a fire. If this is a stock V2 and you are not using a peek fan then y...

Fuse keeps blowing

The first two times the F3 fuse blew, in both cases the black Rambo board fan wire had become dislodged. So I made sure this time to solder it correctly. But the fuse blew again for the third time and LCD went blank right as I click to preheat the hotend. I checked the board fan wires and they had n...
