Re: Project Bondtech Extruder

The PETG print I have been having trouble with the left extruder, has succeeded for the first time.

0.77v
Fan facing the stepper motor (zip tied to the back)
Doors left open.

Re: Project Bondtech Extruder

I dropped mine to 0.6v yesterday, but got air printing 1 hour in. Not sure why. Gears appeared to have lost traction on the filament. Tugging on the 1Kg reel is heavy. No clogging this time.

I upped the voltage to 0.77v. stepper motor is ~40 deg C. now.

Re: Project Bondtech Extruder

Guys, if stepper motor gets to hot heat will transfers from the driveshaft to the drivegear and soften the plastic causing the problems in the picture above. Yep, I realised that as I was putting it back together. I put a fan on the back of the stepper motor, and left the lid off, and it printed fi...

Too hot to handle comfortably, which surprised me.

Re: Project Bondtech Extruder

https://c1.staticflickr.com/1/734/31554184771_53ca6e9005_b.jpg I have recently switched to using PETG, which is my new favourite filament. But sometimes this happens, often an hour or so into the print. I have tried increasing the temperature. The nozzle is not blocked. If I cut away the buckled fi...

Re: extruder clicking

Same here. Since switching to BondTech, my problems went away. However, I did have an issue with some PETG recently, which clogged the BondTech. Tightening the thumbscrew in as far in as I could get fixed it.

Re: Change Start-up code in IdeaMaker

I came here to make the same suggestion. I have to stand by the printer, and wait for it to start, so that I can wipe the nozzle.

The Bondtech upgrade is worth it. Had far fewer problems since.

I think that would be my preferred choice, however I would like to hear your experiences with the kit once you have got it working.

Re: raise uk sakes

Depends on the DHL service. DHL express, or DHL economy. Economy travels by road, and takes a few extra days. Considerably cheaper, especially for bulky items.

Re: X/Y limit switch, failed to limit.

If an unexpected endstop occurs, then all printing should stop, surly? Something is wrong. But your saying there is the possibility of an EMI/RFI issue on these printers, and so it's best to carry on as if nothing has happened, at the risk of damaging the printer. All i'm suggesting is, instead of t...

Re: Power consumption?

Buy yourself one of those cheap wall adaptors, that show power consumption.

I'm working on a USB power meter. It could be used to calculate the cost of each print.

Re: X/Y limit switch, failed to limit.

Yes, the firmware only senses limit switches at homing. This was to intentionally avoid print shift due to false EMI/RFI triggers of the endstops during long prints. :o Can I suggest that this is changed, so that an unexpected trigger of the endstop, forces the printer to reset to home, and then re...

X/Y limit switch, failed to limit.

The extruder somehow moved to the wrong place during a print. It was now printing closer to the home position, that it should have been. I cancelled the print, and the extruder moved to the home position, but didn't stop. The belt started slipping, making a noise for a few seconds. Is the firmware i...

A simple sensitivity adjustment screw might work, with an led. Adjust without any filament installed, for the sensitivity threshold.

A simple IR break beam sensor would be a compromise to detect end of reel. Much more compact.

You only allow this function to work if the print bed is to move down. Never to move up.

Re: Default end of print bed position

3 to set it yes.

2 instantly to move to that location. For example, if something failed, and you had to stop a print.

After a successful print, automatically do a 2 (if the bed hasn't reached that far down). If the user doesn't want this option, they can just set the position to the top (1).

Re: Default end of print bed position

Yes I meant Z. :oops:

If you press the second option, it will drop the bed to your preferred "end of print" position (which it would automatically do after a print anyway)

3 just sets that.
