    Hey guys my name is Angel I’ve been on the forum for a lil while only to browsing for answer and idea for my Robo3d R1 not the plus. I looking to figure out what was the substance use to hold the heat bed wire to the bed? I install a GoPro camera mount and knock the wire off while installing. The issue I’m having is wire get caught between the frame when the y axis move back cause my y axis belt tensor to break a few times. I’m new to the whole 3d printing world and I’m really enjoying it. I know that I should upgrade the bed to the R1+ but until then I want to do something to the wire to prevent this from happen. Also should I just use a heat gun to heat the old gloo up and try to mount it to the side? Would appreciate some help as u guys on this forum are very informative thank in advance

    I used J-B Weld to clue the disc magnets to the glass bed.

    JBWeld is fine, any epoxy should work well too.
    As for the camera, you need to find a place to mount it so that the wires are not in the way of the bed.

    Thanks hoa and mark for the feedback, once I realize what the camera mount did. I did take it off until I figure what am i going to I have been saving to get a touchscreen and raspberry pi 3 to fully on with the octoprint.
    I was wondering has anybody’s connectors for bed fuse together? As I can’t seem to disconnect them I assume this would be a good time to go on ahead and purchase r1+ heat bed first.

    Yes, that can happen if they are overheating. Generally speaking connectors in-line with the bed heater are not a great idea. Even if they are rated for the correct amperage they can get loose and then over heat. If you do use connectors use a good high current connector like a Deans connector

    or Anderson Powerpole connectors (my personal favorites).

    You are welcome :)
    I have 30 amp powerpole connectors on mine and they work fine. Deans connectors are a little more common in the radio control community (powerpoles are more common in robotics). Anything like those will be fine. I would use 30 amp rated connectors and make sure they are soldered well. The bed can pull 11 amps continuous for a long period of time which is what can make things overheat with loose connections.
