Hello all,
I have a strange problem with my Dreamer.While printing suddenly the printhead is crashing into the Z-axis table.Last week I had this many times.
I slice with Simplyfi3D and Flashprint but it is not making any difference.The Dreamer is making collision after collision with my prints.Do I have to reinstall the TF card inside of the printer?
Can anybody help me to solve my problem?
Thanks in advance,
Menno
At what point does this occur? as in how high have you printed before it starts crashing into the print?Quote:

does it have dual extruders ?
Could simply be that they are not perfectly level. In which case one nozzle will pretty much always drag bits of the print around.
It has nothing to do with leveling or extruder hight.Well the problem occures random with almost every print while printing.Yes all my print starts off ok.I tried different models to export with several CAD Design software (Siemens NX,Solid Works,Mastercam).That could not be the problem.
I did some research and I found out when I slice with Simplyfi3D and save the G-code on the external SD card all is fine.In Flashprint the same crashes when I sent the G-code via usb.So when I sent G-code via usb the file would be stored on the internal TF card and I think that is the problem.Maybe a corrupt TF-Card?
sounds more like an issue with flashprint to me.
No.Read my first post.I slice with Simplyfi3D and Flashprint but it is not making any difference.
So something is stopping the Z height from progressing..Quote:

You have been through all the google groups with the thousands of people that have had the exact same issue?

Geoff first of all I want to thank you for helping me to solve the problem.I want to show a picture but in some way I can not upload it.
Yes the printer is homing properly.No strange noises all is fine.Well I can not find anyone who have the exact same problem.They all have problems with stopping during mid print not hardcore crashes into Z-axis.I also posted this problem in google groups with a picture.

Would love to see a video of this taking place.

I've also read many other people having problems with it at various times, without any 'rhyme or reason'. I suspect you have a problem with the USB communications, either in the printer, computer or USB cable..?
No No,the TF-card is the little micro sd card on the motherboard.When you transfer the G-code via usb it will be stored on this internal flashcard.I know Flashforge has change de VID and PID for usb after a firmware update.So we can not use Simplyfy3D anymore over usb.And what is Flashforge doing to solve this problem?Totally NOTHING.We wait for months now to use Simplyfy3D over usb.I rolled back to a previous firmware to use the software. You can see the threat in the link.
Oke but that is not solve my problem.I am a CNC engineer so I think I have to check the G-code in the file.

Ah ok, thanks for the information, and holy cow what a mess.Quote:

If that's the case then I think you are on the right track with your diagnostics, and a closer look at the TF-Card is needed. If the control set does copy the .gcode to the TF-Card when SD-Card printing then I think the problem is unrelated to the TF-Card. I know, I know,... Not giving you any help/information you don't already know.. :confused:
Please let us know how you make out.
Hmm very odd issue indeed, I wish I could be of more help, but since the dreamer is then streaming it's own file after the gcode export, it's hard to tell exactly what it's doing.
is that big blob in the corner of your print a result of it being knocked off, or is it the reason it was knocked off?
The blob is the result of crashing from Z-axis into the print not from knocked of the print..I suspect that if it crash it also extrude a lot of plastic at the same time.I went to the G-code file and found sofar nothing strange.I saved the file from the internal micro sd card to my computer.I will copy that file to the external Sd card and run that file...see what happens.I think I have to inform Flashforge also.
[/PHP][/PHP][/PHP]PHP Code:[PHP][PHP][PHP]
I does copy the file but not properly.The crash is at approximately 2.5mm while printing.I went into the G-code file and search for Z-movements.I can not see strange any coordinates in the file.When I print from external SD card sofar printing is fine...fingers crossed.I do have to make some tests and try to understand why this problem occurred.Also I reformat the internal sd card and put the required files on it.The printer was booting up fine.Oke first I have to do somemore testing.Can I upload also G-code files?Quote:

So why not just do that ?Quote:

I mean if doing it one way means it works and doing it another way means it does not work - then don't do it the way that doesn't work.
What do you expect to gain by using the method that doesn't work - ie: why persevere with it ?
