Welcome to the SeeMeCNC Community

oh...christ. Yeah, i'll tack some of that red RTV around the ends once my current print stops. Was kind of thinking of that when i saw the epoxy was rated for in excess of 150c, but didn't think of how far in excess.

I just swapped out some burned up resistors for a friend. Same symptoms, one day the machine just wouldn't heat up as fast and couldn't quite reach its target temperature. It looked to me like there was an airgap in the silicone that allowed the resistors to heat up without transferring the heat in...

The power resistors are quite fragile, and if you are not very careful when assembling the hotend (IE if there is a small pocket of air next to one of them) they can build up too much heat and rupture. The cartridges are so much more robust, and I'm sort of disappointed that SeeMe still hasn't desi...

I don't work on the printer with the power on/connected when i work on the printer since i blew the heater fuse. I removed the wiring from the board and verified, 9.8 ohms. I have a 12v heater cartridge lying around from an e3d hotend i have sitting in a soon to be replaced rigidbot. i might give th...

yeah, its run about 3 kilometers of filament now, primarily ABS. I turned it off a couple days ago after leaving it on for a while (board only, hotend and HBP shut off automatically), came back to it today, and it was doing this. Both resistors are running in parallel, i promise.

I'm getting 9.4 ohms when i touch the two sides of the resistor package. Do i need to unplug the wiring from the board when i measure, or am i actually getting 9.4 ohms?

max duty is set to 255. I also tried changing the fuse, now gets up to about 187, and about 207 with the fan at half speed. i feel as though there might be something wrong with the wiring or the resistors for the extruder

I'm having a frairly worrysome issue with my rostock max v2. At the moment, i cannot get the hotend past 160 degrees without having a nice piece or two of kapton tape nearly completely blocking off the extruder, at which point, it will heat up to about 1 degree below temperature and stay there. I'm ...

i mean, yeah, you can do that, but isn't the potential there to have the second print slightly off from the first after homing??

I am attempting to print a 1.2kg part :shock: on the rostock max, and was trying to verify the home position on a test part. I let the printer get through the first layer, start the second, and hit pause. The printhead lifted, swung way off to the side, tapped 2 of the endstops. When i went back to ...
