Re: What is your experience with the HE280 hotend?

Once I worked out the self induced bugs like not installing the PDFE in far enough and having the retract too large it has worked very well for me. Oh, and after I install some Kapton tape to block the hot end cooling fan from spilling air onto the bed causing lift problems with ABS. I only print AB...

Re: HE280 Keeps mysteriously clogging

The two most common causes of that are
1. The bowden tube is not seated all the way down inside the hot end.
2. The retract is too big. For the hE280 it must be very small. Good value is 2mm and not much more.

Re: Where do I set the Extruder Temperature?

Or Maybe you don't have the Start G-Code defined which sets the printer temp.
Mine has
M104 S[temperature]
M190 S[bed_temperature]
M109 S[temperature]
G28

Re: Where do I set the Extruder Temperature?

Take a look at the gcode produced by using the save to folder option. Perhaps you will see two extruder temp settings in that. One that you desire and then the one that gets set by the printer. Maybe they are set in the predefined custom g-codes under printer custom g-code.

I can't answer all your questions but No there is no firmware for this printer that have LCD commands for movement other than those you already found.

Re: Extruder Stepper Issue

First try it with no filament in it. If it turns then it is probable that the is a blockage in the hot end. Also remember that it will not turn the extruder until there is a minimum temperature reached by the hot end. If it does not turn try swaping its cable with one of the other stepper motors to ...

Re: New build, major calibration issue. Crashes to bed.

It looks like you may have the EEPROM settings for the bed size too large. Check that the max X length and max Y length are 250.

Re: Automatic Calibration Crashes/Freezes/Broken

That kind of behavior is more likely caused by loose wiring or pins that gets triggered by the movement of the carriage to the side.

Re: Non HE280 accelerometer upgrade

The way the rambo firmware uses the accelerometer is not the way you expected. What it does is use the i2c interface to setup the accleerometer to set the INT line when the acceleration exceeds some threshold. Then it monitors that line only during special moves during the calibration process. When ...

Re: PEEK hot end failing

The resistors don't ever seem to last very long. I eventually changed over to a heater cartridge. Then I upgraded to the HE280, If you don't want to do the upgrade I have my old hot end with the heater and good thermistor that I could mail you for free. If you want.

Re: New with a pile of parts

Welcome, I'm glad for your enthusiasm to make something but it looks to me like you don't have enough of a machine there to do that easily or cheaply. From what I can see you are missing some very important parts like towers and belts and things to hold them together correctly. The parts you do have...

Re: HE280 question

That usually means one of two things. You have the retraction too big when using abs or you did not get the bowden tube seated properly. Usually it is the latter.

Re: HE280 question

Yes. They needed an extra wire for the sensor and so stole it from the fan and then connected the fan up to power so that it would always run.

A recent poster talked about his motors no longer working. Turned out the little Red Jumper on the power connector to the rambo board was loose and so the motors were not getting any power. Check that jumper.

Re: HE280 upgrade problems. Need help!

With the new software your shop temp is too low. That is being reported by the machine and it will not work until you change somewhere in firmware that checks the temp value. IF it gets lower than X it will think the thermisters are not working and thus should not run. There are some threads in the ...

Re: Fan Direction after Upgradeing to 29amp PS

I think you installed it backwards. Mine exhausts the air as per the build instructions I think. There is an arrow on the fan I think that shows the direction and the upgrade instructions tell which way it goes.

Re: Firmware Updates?

Perhaps you have a g code at the top of your files that was ignored by the V2 firmware but now is no longer ignored. Maybe post you initial g-code from the file for the first few commands until it really starts to print.

Re: Firmware Updates?

V2 and V3 share the same firmware. Only the configuration.h file is modified for one or the other.

I do not have that problem with the December release. So if you wanted to try that version of the release it may work for you. That would partly isolate when the change happened.

Thanks for the explanations. What the printer does when you cancel is (I believe) set by your slicer or printer control program. For instance I use Octoprint or MatterControl. When canceling a print from either one my V2 does not reverse the extruder. I'm using the December release. I could not find...

My only recourse is to hold the EZRstruder until it stops. This seems to happen from SD, Octoprint, and MC. 2.) When starting a print from Octoprint, f...
