I checked the content and it's there and I have tried not turning on the hot bed and hotend. Funny thing is it prints when I teither it by usb and use simplify3d. But the calibration doesn't actually do anything and results in a very high nozzle. I just find it weird that it was working perfectly fine before and i was printjng everything then all of a sudden this happens

Ok so I tried it and placed T0 in the start up section on two gcode files that i have printed before and still didn't do anything stated it uploaded 100% printer doesn't re-home and start calibration and both the bed and hot end switch off and start to cool down.

I'll give it a try tomorrow but I don't understand why it is doing it all of a sudden, but I will see maybe I'll just but it in the start file from the beginning, And see if it works thanks deckingman

So I'm in the process of fine tuning my Prints and I have started making some parts for my car.
Finally get a good model happening and when I Hit the button to Upload and print. It up loads the Gcode file and then turns the hotend and bed off and tells me the print has completed.

The printer doesnt even home or try to do a preprint calibration.

I was printing 2 days ago turned it off and then came to print today and got given this.

Any ideas?

this is on my Custom Kossel XL.

Yeah I have I think the issue is that the z height keeps ending up being to low even after recalibration and re adjustment of trigger height it still ends up squishing after to much so it creates pressure in the Bowden and also buldges on the outline layers problem is I do t know how to fix it.

Yeah I have seen his channel I like his videos. Iv managed to print simple stuff now but I tend to get blobs and so own that harden to the point that it actually ends up knocking the effector off the rods well printing.

Here's what I can print with ease.

But this is the problem that's happening. Don't know if you can see it.

My Bowden tube is just over a metre long but I had this issue before I set up pressure advance the small cube is what I was using to calibrate the pressure advance. Burtoogle I'll remember what you said when I do print pet.

@burtoogle:

Hi, it looks like you are using PET which loves to glob together into little balls that then stick to the extruder and cause problems. For PET I am using 235-240 nozzle temp and 80 for the bed. If you are using Cura to slice, turn off combing as this tends to produce dribble which forms balls as mentioned above. Make sure the first layer isn't too near the bed, PET doesn't like being squished down. And don't go too fast, I am using 30mm/S for everything except infill which is 40mm/S.

Hi I'm using the colour fab violet translucent pla and using simplify3d without coasting and wiping but I have pressure advance set to 0.5

So these are the prints I'm able to make with ease but as soon as I try and do anything more complicated It seems as if I'm either over extruding which I have calibrated and all seem good I have am also capable of printing the parts mentioned above.

I also thought maybe the nozzle is to close to the bed so I had adjusted my G31 z parameter lower to move the nozzle up higher but I still get this issue which seems to knock the effector off the magnetic rods.

So any idea of what's cause these random blobs every where.

I think it's the z linear rail as after I do a calibration I home the printer then go to check the z height and it's set too high.

I have changed my Step/mm to 100 as DjDemonD suggested.

I have a Feeling its the linear rail on Z now that you mention it when I was installing it it didn"t seem quite as smooth as the others so i washed the bearings down with brake cleaner and re-lubed them with some lithium grease rebuilt the carriage which seemed to help but i guess it wasn't enough. luckily I have some Hiwin Linear rails coming to bad they aren't black but function over form

Ok I tested the trigger height 10 times now and 5 times it came up with Z1.363 and 5 times it came up with Z1.403

I was going to just test it 5 times to make sure it was consistent but on the 5th time it came up with Z1.403.
So I did one more test as piece of mind and it went back to Z1.363. then from the 7th time to the tenth time it produced Z1.403

So ill use 1.403 as the trigger height since it was the last set that showed up but is this something that I should be worried about?

@dc42:

If you still have problems when you try again, let me know which step you get stuck at. You mentioned "night and day" - are you sure that the IR sensor is giving a consistent trigger height regardless of the lighting conditions?

Yeah I followed your guide on checking for consistent triggers and it aligns to the guide. I finaly have a few hours to work on it so ill start fresh with endstop adjustments set to zero and see if it will play ball today.

Thank you David

I just want to print something haha

Thank you David, I did try that last night following your guide and it didn't help but this printer seems to be like night and day, and today is a new day so I'll try again when I get home.

Thank you for the help.

Ok sadly this thing has decided to act up once again. I managed to get some time to sit down and try the cube test. So I figured I'd double check my z height and do another calibration preprint.

With the paper test the height still had 40mm to go before it hit zero. So I 're adjusted the height within the config file and double checked it.

It was paper perfect, so I thought ok time to auto calibrate and it came back with a devation of before 5.002 after 1.236. Then I recalibrated untill I managed to get it down to 0.2xx I can't remember exactly. Then it climbed all the way up to 9.xxx.

I restarted the printer to get back to the 0.2xx that was saved And tested the z height and once agian it wanted to go through the bed.

I spent about an hour going back and fourth with this before I lost my temper in pure frustration I turned everything off and walked away. This is what it was doing before the rebuild but now I have no idea what to do because it feels like it just doesn't want to work.

What do you guys think is the issue?

Thank you so much guys I really appreciate all the help. I'll keep this all in mind when I can finally get to do the test prints on Friday.

Thank you guys so much for your help I was pretty much ready to just bin it and give up. Also the information you provided has helped full most of the black hole in my understanding of what to do next.

I'm running gt2 belt and pulleys that are 16 teeth with 1/16th stepping.

As excited I as I am to do a test print I have to get ready for job number 2

Now what makes it a good result? is it the deviation being as low as possible or is it to do with with the m665 results being close as possible to the M666?
