Ghost comes unstuck from the bed during printing  

Re: Ghost comes unstuck from the bed during printing

yaa glad to hear it. I wouldn't give up yet, save the hardened nozzle for later or when you have time to play around. if it helps my 200% ghost failed while I was at work. needless to say im setting up octoprint so I can stop the printer when away from home. 5$ for pi zero w. I also got a real pi 3 for my webcams. cant beat 5 bucks

Re: Ghost comes unstuck from the bed during printing

Hi Breazile,

there are many ways to change the printer's performance, you had difficulty with a hardened nozzle, did you try raising the filament temperature a little. ? say 5 degrees...

I printed my ghost with a stainless nozzle at standard temperatures but slower than normal.... the value I referred to as feed, is speed on the settings menu.... I just dialled the number back on the main screen. without going into the settings menu.

with the stainless nozzle I perhaps should have raised the filament temperature a little too... but it worked fine... as I was out of the house, I wasn't able to 'up' the speed to 100% after the skirts bridged, however as there was no rush, it wasn't a problem.

regards Joan

Re: Ghost comes unstuck from the bed during printing

trust the Joan. i have no idea why my crazy fast speed worked on that print. looking at the model it should have failed for me more. guess thats what happens when someone is beyond bored printing one material at a time. someday ill get my MMU. i bet i have to lower my speeds back to default, but im willing to try

Re: Ghost comes unstuck from the bed during printing

I ordered a lot of different nozzles from E3D, so I'll play around with them more. I have brass, stainless, hardened steel in various sizes. For the steel one I dropped the temperature, only once did I raise it. I think the nozzle was loose as well, it came off easy. I tightened it with the 3D printed wrench I made. I used a real torque wrench when I put the brass one back on. I'll have to play around with them more to understand how to get good prints from them.

I have the raspberry pi for the octoprint, but have not installed it yet. Waiting on the long pin headers. Adding a camera would be great, too, are you adding that to the octoprint somehow?

Hopefully my MMU2 comes in November.

Re: Ghost comes unstuck from the bed during printing

im slowly working on getting my endoscope working on my pi. 100% Linux noob. so it might take awhile to get it going. im not even gonna try with the pi zero. but at least the zero works. 5$ cant go wrong. thank the gods I didn't have to take apart my einsy case.

Re: Ghost comes unstuck from the bed during printing

hey, my daughter was trying to print the ghost with her settings. she was failing until I turned off Z hop.
I have it turned off unless im doing manual MMU crap. I mean stuff... no crap.. manual is lame. more then 8 layers.

Re: Ghost comes unstuck from the bed during printing

I tried the new INI settings, but that did not really help. The printer did a weird thing where the extruder went to the middle of the build plate for 5 minutes targeting a temperature of 140. I thought it crashed, but then it moved to do the wipe, and waited there for it to heat back up to 195. That caused a filament jam. Tried that 3 times, then made sure the bondtech gears were clear and moved back to my original settings.Sorry to be late to the party. That's my printer profile. What's going on is that the 140C temp is set so you don't get ooze droplets during mesh bed leveling. Then it moves the head to the bed center with the bed temp set to 65C waiting for the PINDA probe to warm up to a consistent 35C for better mesh bed levelling results. When the PINDA probe hits that temp, it homes and does the mesh bed leveling. Once that's done, it warms up the nozzle to full printing temp. Unfortunately, the Mk3 firmware doesn't let me print helpful messages on the front panel as this happens, so it can appear stuck. Detailed notes on what's going on here.

I do not get jamming once the nozzle is up to temp, though I tend to print at a higher temp (200C and up). Does the jam occur immediately?

I'll try the Prusa PLA settings from the new INI, it looks like the temp is about 10 degrees lower. I think the key will be with getting the right temperature, and retract settings right. I have only had the printer a week, so I'm still learning all of the settings.
When in doubt, revert to the Prusa profiles. Mine are under constant development, and are intended as starting points for experimentation, particularly with different nozzles. I'm currently tweaking them to fight stringing.

Thoughts on your little blobs:

Re: Ghost comes unstuck from the bed during printing

I ordered a lot of different nozzles from E3D, so I'll play around with them more. I have brass, stainless, hardened steel in various sizes. For the steel one I dropped the temperature, only once did I raise it.I find I don't have to change temps much for hardened steel. I generally keep either a 0.40mm or 0.60mm hardened steel nozzle mounted most of the time. Stainless nozzles don't gain you anything unless you're worried about food-safe prints. I do like the nickel-coated copper nozzles for fine (< 0.35mm) sizes as they're supposed to be less prone to filament build-up.

I think the nozzle was loose as well, it came off easy. I tightened it with the 3D printed wrench I made. I used a real torque wrench when I put the brass one back on. I'll have to play around with them more to understand how to get good prints from them.A loose nozzle will definitely cause problems. E3D nozzles will be pretty consistent, but I always recommend doing a Live-Z adjustment any time you change nozzles.

I have the raspberry pi for the octoprint, but have not installed it yet. Waiting on the long pin headers. Adding a camera would be great, too, are you adding that to the octoprint somehow?I'm just using MotionEyeOS on a Raspberry Pi Zero for video. Octoprint is overkill for my needs at the moment.

My notes on nozzle sizes here. I'm personally a big fan of using the "right" nozzle, as any nozzle distortion is going to show up as annoying-to-troubleshoot inconsistencies later on. I use hardened steel for larger nozzles (0.40mm and up) and nickel-plated copper for smaller. Nothing wrong with using brass for everything starting out, but just keep in mind they will abrade eventually. At least you're using E3D parts which are a lot more reliable than the cheap nozzles off Amazon.

"the Mk3 firmware doesn't let me print helpful messages on the front panel "

im guessing that's for the best....some people might have too much fun with that 😀

I'm reduced to making little chirps to let the user know the printer is alive. Need to hook up some over-complicated IoT solution.

Re: Ghost comes unstuck from the bed during printing

every time I put fancy beeps in my Gcode something happens like I loose all my settings so ive stopped doing that,
but I have only had 3d printers for 4 months, but decades of 3d max fun.
