Re: HE280 hotend upgrade stuck

I'm just wondering if I should run a PID auto tune for the new thermistor.

Re: HE280 hotend upgrade stuck

Thank you for the tip. I was betting on a pinched wire or a bad solder joint. I don't think I would have caught the polarity on the connectors. Both the blue and the red lights on the hot end light up but none of the fans were spinning. I really appreciate all the help the forum has given me since I...

Re: HE280 hotend upgrade stuck

OK well one problem solved and onto a new one. I rechecked and remade all me connections ( used a termination strip instead of soldering them) and now it moves. The new problem is my Y axis motor moves downward as the other two move up to the homing position when I run the calibration script. I doub...

HE280 hotend upgrade stuck

HI all, I have built and installed the new hot end, reflashed the firmware and now my printer is stuck. It powers up but will not move off the "title" screen that you see on startup. I tried reflashing the firmware and changing the printer type to "5"( maxv3) with no change. It w...

wiring diagram for HE280 hotend

I'm ready to install the new hotend on my V2 but the wires will not reach down to the RAMBO in the base. I was going to put a term strip on the top as a connection point between the old hotend wires coming from the RAMBO to the new hotend harness. Is there a diagram to help me out with that or a bet...

Re: HE280 Hotends now on the website

This comes just in time as I was going to pull the trigger on a E3V the next time I seen a sale on them. I'm frustrated that the wiring harness and the Hi-Temp Jet Kit for HE280 Hot End are out of stock. Also I am curious about spare nozzles. Apparently the stock nozzle will not work for the new hot...

Re: Thermal shielding for berd air tube

I have been mulling over whether to get an E3DV6 or stick with my modified stock hot end. I like the idea of using the Ultra copper silicone. I think Ill put a layer or two on the top of the berd air clone.

Thermal shielding for berd air tube

I made my own berd air tube and after installing it I was wondering how much heat is transferred to the brass tube due to its proximity to the hotend. That led me to start wondering if there should be some kind of thermal barrier between the two. Or am I just over thinking this?

What is the size of the wire loom?

I have added a Berd style layer fan and a few more wires going down the bowden tube and want to clean up all the potential snags. looking around on the web has me thoroughly confused as to the size i might need. Thanks in advance.

Re: Nozzle temp 5 degrees low

The thermistor reads 115 from the plug at the board. I am completely mystified by the software side of all this so I was leaning on Xenocrates to help me with the firmware changes. That being said I am not 100% confident I did as instructed. Silly question, the thermistor has no polarity correct?

Re: Nozzle temp 5 degrees low

Its still stuck on the nozzle temp being 1024. Do you think I should change the firmware back to the original and work from there?

Re: Nozzle temp 5 degrees low

It could be the configuration changes you just made, but assuming those are correct, you either have an open circuit or a short in the thermistor wiring. Disconnect it from the board and measure the resistance with a meter, it should read ~100KOHms at room temperature. If you think it's the firmware...

Re: Need help deciding on new hot end

Ok well I replaced the thermistor and the resistors, flashed the firmware and now my nozzle temp reads 1024. The display on the printer reads "DEF" for both the nozzle and the bed. Where did I go wrong?

Re: Nozzle temp 5 degrees low

Your a brave man, I done see much real estate to drill and tap a hole with. I was also thinking about using duct tape( the metal kind). Did you fill in the hole on the opposite side with anything? I was thinking it might be a good idea to help keep the temp more stable.

Re: Nozzle temp 5 degrees low

As a follow up, I had a bad resistor. In the process of doing to Geneb upgrade. Is it still recommended to wrap the ceramic heater in foil or would I be better off with high temp RTV? Wish me luck.
