ARGGG! I've set my towers and z height as per the instructions. When I run a print, the hot end nearly gets to the table, then moves upward about 1cm...There is where it starts to print. I tried to calibrate the z height many times. Some times it slams in to the table, moves upward about a cm, then ...

No! I set the z height twice, from the LCD screen, to be sure it took. I did print from the sd card. I've gone through this process 100 times on my rostock with perfect success. I can guarantee you that I'm doing it right, no question. Something is interpreting the Z height wrong, somehow. I'm going ...

I just tried to run a print with the original suspect gcode and the head ran into the table. It has to be firmware. It's not interpreting the gcode properly in Z somehow.

JFettig Thanks for your input. I recreated a 1" cube in Autodesk Fusion360 (not Solidworks) and used Cura (Not matter control or Repetier) to slice. I reset my z height (same "Z" number as I got last time) The hot end ran into the print platform. The graphical cylinder that represents the build ...

I'll look at that! Thanks! I'm gonna open my rostock and big printer's firmware and compare them line by line today. I hope I can find the culprit.

I believe that definition is for Cartesian machines only? Could be wrong. Mine reads: #define XAXIS_STEPS_PER_MM 98.425196 //98.425196 /** \brief Number of steps for a 1mm move in y direction. For xy gantry use 2*belt moved! Overridden if EEPROM activated.*/ #define YAXIS_STEPS_PER_MM 98.425196 //98 ...

I didn't measure with jog actually. The printer is at work. I'll try that in the morning. Let's say for now that it moves 5mm in your example, what's on your mind?

It's a modified Rostock Max. The firmware is stock, other than It's been modified to use a GLCD instead of the standard LCD. I don't have any pics as of yet. Just some things I've tried... I've moved the head to Z100 from 0,0,0 and then used M114 to get the position, which was the same, but when I ...

I tried printing a 1" cube. The X and Y dimensions ARE 1" but the height is only 1/2". Yes, it finished. The top is capped off. Any clue as to what I need to do to increase my overall height? Each layer is squished as well. I'm running a 1.5mm orifice and my layers are supposed to be 1mm, but they ...

My peek fan works as it should, "virtually connected to the hot end power". My layer fan runs intermittently when I manually turn it on while the print is running. Shouldn't it run as long as I have the button clicked? It does when a print isn't running. Is there a gcode that is defaulting it to off ...

After finishing my new Rostock Max with Trick Laser mods, am now printing my second part. I've always wanted to try to print ABS on Scotch Super 77 spray adhesive. It works great! Don't use 78, it blobs when it comes out. 77 sprays nice and fine. It works much better than the purple stick. Give it a ...
