Multi use machine.

Former Member

Hi,

 

I am trying to build a multi use machine that is able to do:-

 

1. 3D printing.

2. spindle engraving/milling of soft wood.

3. laser cutting/engraving.

 

at the moment i am almost finished the main mechanical parts and i am getting ready to install the electronics, my main problem is that from what i see on the net almost all mills/engravers are run via Mach3 and most 3D printing is done via Rep Rap, I have both of the boards available to me and was going to install both of them and then just unplug the one i was not using but i would like to be able to just install one system for all usages which i think will have many less faults than installing both which is the only way i can think of at the moment, does anyone have any ideas as to how i can do it with just one system?

  • Also, the problem with adding 3 extruder heads or tool heads is weight... You may need to make the z axis (up and down) dual, two motors and two screw drives, you basically have to wire two kysan motors together to one plug for the z slot on the printer board. This way it will be able to carry the weight of 3 tools, if you look at Printrbot's larger printers, this is how I would build it. It's difficult to calibrate dual z axis but a single z axis will sag which I found this out on my simple that I upgraded.

    Hi Brad,

     

    I was not going to mount all three heads at the same time I was going to make it so I fit the required head as needed but even if I fitted three at the same time the motor I have along with the rails should be able to manage the extra weight of all three heads the laser unit is very small and only weighs 25 grams, the extruder weighs 39 grams and the spindle motor is just over 1 KG the motors are NEMA 23 and have 30kg cm torque  so they should be able to handle anything I mount to it, i still have to fit the cable track/chain along with all the electronics which i have already bought except for the box to mount them in as i still need to set them out to work out the required box size.

     

    i just looked at Printbot's printers and this one is a much heavier built machine.
