We've just finished the support materials for the 3D printer. The 3D printer is now fully operational on Mach3. We have made Macros such that the system is now compatible with the default output from STEPCRAFT Repetier Host Gcode file. You have to make sure that the 3D printer motor in the head does not wind the spool backwards. This can cause the spool to clog when filling back up again. The two MAcros we have made and that are now included as part of the installation pack Zero the 4th axis at the start and end of the Gcode file.

hello Rory,
I watched your video and think it's great.
Also use Mach3 and would also like 3d print ...
is the installation pack for free?

thanks for the help

Rob - did you email us? We had an issue replying to an email a few days ago...

Glad you like the video. Please let us know if anything is not clear.
Please see the XML.

you may use it as you wish - we can provide support here on the forum when we have time.

there are two Marcros that you need to copy to the Macro folder - see video. For some reason can't attach the Macros to the message. The Macros zero the A axis before the program starts. be careful here - don't allow the A axis reverse when you start the program (always 0 the A axis) this is what the Macros do. Otherwise it will wind the filament in reverse and this can be very tricky to fix/clean/get going again.

If you do use our files - we ask that you share the results back with the community. Email us and we will share the macros

We are waiting for a small addition to the Repetier software (for generating the 3D printing Gcode) as we need a small change to allow the cooling fan to work 100% correctly.

Hi Rob - welcome to the Forum!
I'm not sure which browser you have in use but with a (mouse) right click on the XML file link a context menu will pop up and there must be something like "Save Target As ..." or "Save Link As..." or something similar. That should work to save this file to your Computer. If not try the other options in the context menu - one will definitive work!


Good luck!

It's not only about tools it's also about skills! ;)

Seriously, Chrome for MAC has not the same right click context menu like the WIN version ... :huh:

You need the macros too.

otherwise the A axix will not zero itself when you run - watch this. Its a b*** to reset the printer head and get the filament going again.

always zero zero zero zero the Axis before you start...!

the macros do this at the start and end of program to be sure

We have made macros that zero the A axis before and after the program is run. to avoid spooling in reverse when the A axis goes back to "zero".

dropbox link

Here are the Macros. There are two in there that should "zero" the A axis when the program starts and finishes.

Hello, I am a new customer and new to 3D printing. I am still a little confused by the Macros. What do I do with the files in that dropbox?

I am also having a little trouble with my printer material, I am running at temperature setting of 170 and the part is being distorted. I feel like I have the temp set to high. Where would you suggest the temp setting should be?

Thank you,
Ian

It is very important that the 4th axis does not "spool in reverse" when you control it. this will wind the filament in reverse and pull the plastic out of the nozzle. I've done this. It's a NIGHTMARE. you will notice in the Gcode from teh repetier host that there are M107 and M109 commands. We simply made these commands zero the A axis. This means when you start / finish a program they will zero the A axis,

apologies - Here are the macros for MAch3. You need to copy these to the folder on your C drive.

Explanation here.



you need to play with the settings to get the warping corrected. Limited experience using the 3D printer system. Perhaps someone could help?

There is a small final tweak that needs fixing in that the fan is currently not controlled 100% by Mach3. It has a 0-100% setting in the 3D printer head. this needs to be controller by Mach3.

Hello,

i've purchased stepcraft 300. I use it to mill and 3D print with Mach3.

For milling, i've no problem, all it's correct.

My problem is with the 4 axis for 3D printer. I use a LPT1 connection, and i don't find the correct parameter to control the PLA feeding. I need the correct parameter for pin connection and the motor parameter (speed,...)

Thank you for your reply.

Kind regards

David

See does attached file work. NOTE: you should really have the Macros too (can't upload them to here for some reason)... send us an email.

we have a M107 and M109 Marco setup to zero the A axis at the beginning and end of a print cycle to make sure the nozzle doesn't reverese itself.
