Greetings,
Here’s some detailed info on my Form1+ resin heater build. This should work fine for regular Form1’s as well
Overview of heating unit setup, with thermometer orange light on (light goes off in a couple minutes, but digits stay visible)
Thermometer probe location detail. I had to bend the probe a little tighter to get it to fit lengthwise into the tank.
Heater wire/Thermocouple detail view. Tan is silicone heater wire, black is the thermocouple for the controller (controller not shown, outside of printer. See BOM for link to controller.) The tan stub sticking up in the corner is the end of the heater wire.
Target temp left, actual temp right. Timer on bottom if you need it. Overall a very nice probe thermometer. It came with a self-stick magnet, but it was wimpy, and the self-stick came unstuck. I bought high-power magnets, and epoxied one to the unit. I use the other extra magnet, plus the one that came with the thermometer on the top of the Z-tower to hold the heater wire lead and thermocouple wires out of the way, and direct them out the back of the cover.
Not visible, I used a 1/8" thick piece of neoprene gasket material to pad out the hinge of the orange dust cover. This gave me just enough room to allow the cables out the back of the dust cover, without misaligning the hall-effect cover switch.
Clip used to affix the heating cable to the tank walls. The stagger of the wires makes the resin have to cascade between the wires, enhancing the heating thereof, and keeping the wires low in the tank. The resin is really low in these photos, and I would add more before printing again.
Attached is a compressed form file. It’s really a zip file, so rename it by removing the ‘.form’ extension. The upload feature won’t allow zipfiles, so I had to rename it to upload it. The form in the zip has 12 clips already arranged for printing.

Bill of Materials
It should be fairly self explanatory, but post if you have questions.
