You should probably do a test to see if your switches are actually getting triggered.

Close the switch with your finger and send an M43 command. It will tell you if the firmware is detecting a trigger event.

I spoke too soon. My new, beefier switch has now pooped out as well. Didn't melt has obviously as the smaller switches, but it is definitely the switch.

If the extruder head is making erratic movements, I would think you are dealing with a communication (over USB?) or controller issue.

Haven't had this happen on my Hictop, but it has happened plenty of times on my FFCP. Instead of removing the print head, just heat it up manually and slowly pry away the excess PLA. Because it heats locally around the hotend first you can usually pull it off in a single piece. Also, acetone will so...

Ok, finally got a voltmeter and poked a bit. Turns out, the signal stops right after the power switch on the control board! Nothing melted though, so not sure what happened. I'm hoping HIC will replace the switch. In the meantime, can I simply just bypass the switch and wire the power supply right ...

The first two switches (the original and a replacement I bought)I had on my 3DP-12 melted. They were simply undersized. HICTOP eventually sent me a new control board cover with a beefier switch. Give a sniff around the switch and see if smells like melted plastic.

Just tried with 1.8.2 and did not see this error. Must by OS specific (I'm using linux).

This is an old post thou someone else may have similar problems. 1. The LCD control will not move the Extruder until the nozzle is up to temp about above 170-180 degrees Celsius depending on software settings. 2. This could be because of the solder connection between the thermistor and wires. A Mor...

I have successfully compiled shockofmighty version of Hic firmware Marlin-RC8BF-HICi3. Question to see if I understand the firmware. Line 268 and 310 of configuration_store.cpp, if I understand Microsoft's description c_assert is a test for assertions at compile time. So the errors during compiling...

Another thing I discovered last night is that if you are doing PLA at temperatures above 210, you have to turn down the cooling fan as well. Once the fan kicks in (usually around the third layer), it can drop the extruder temp by +10 degrees, and it will take almost 10mm to recover to 210. I never ...

Nope. I only have one extruder, and there is only one listed in the Config.h:

I recently just added heat-resistant cotton around my hotend. This makes quite a large difference. The stock cooling system isn't really all that well designed, and a large amount of air goes right over the hotend, instead of toward the bed. Another option, just turn the fan on at layer 0, which is ...

Good catch, GrueMaster. After you mentioned this it rang a bell. I didn't notice when I looked through Config.h. That's because I changed values in Config_adv.h! The issue I had was when the cooling fan came on, there was a pretty big temperature drop on the hotend, and it would fall out of this ran...

No such issues, but most likely related to your heated bed since that seems likely to be the difference between the two protocols. It is possible that it is a different thermistor type on your heated bed. Check the values from the original firmware and see if you might need to change that.

The '98 ready' is just because the name is too long. You can change it in the firmware. #define CUSTOM_MACHINE_NAME.

EDIT: Filament run out sensor was certainly OFF in the firmware I distributed (//#define FILAMENT_RUNOUT_SENSOR)
