Does anyone know where i can gind info on building a large delta printer? For instance what rod size and what size ectrusions needed and such.

Are there any guide with instructions and a bom for building a large format kossel like 300x300x300. I have motors and a duet non wifi with it probe. I also have a bunch of solid v-wheels. Amy help would be great.

When i was using the ir probe on my old kossel it would usually crash into the plate if i made changes to the parameters. Would new firmware fix this?

Ok, I sorta get that, thanks for pointing me in the right direction. So as long as that command doesn't exist than it will map how I set it up. Merry xmas dc42.

Here is a question, how come I cant convert one of the extruder port for a second motor?

@StephenRC:

Not all the wires from motor 1 go through motor 2. Interesting, googling a wiring diagram that works for a 3d printer isn't all that easy.

This should help: http://rigidtalk.com/wiki/index.php?title=Z-Axis_Stepper_Motor_-_Series_Connected_Splitter_Board#Why_Series.3F

I really appreciated it. So all i need to do is connect the wires shown in the diagram? And use the connector you listed to connect the in the order shown?

So further looking at pictures, I am assuming that wires from motor one go into motor 2 and then out of motor 2 to a connector?

@StephenRC:

You could get something like this to make the connections: http://www.digikey.com/product-detail/en/on-shore-technology-inc/ES1000-12DSFB/ED3006-ND/2720753

Cut off the current connectors a few inches from the connector on the motors and use the terminal block with one of the cutoffs to wire them together without any solder, to connect the motors to the Duet.

How exactly would I use that connector? I am not grasping the concept. So how would the wires connect? there is really no clear info for those who are trying to learn basic electronics, does each color wire get connected together? all I see is a small board that you have to make and that's all I get from it. Is there a pre-made thing I can use?

Well that is beyond my skill level, I suck at soldering and also manipulating small wires with my eyesight is horrible. I can build a printer with no issue I have built 2, I know very basic limited electronics, enough to get by. So I guess I need to find a different board for my printer I want to build instead I want to make a omerod style printer or mayne add a second z axis with a belt system.

Last question, when using the ir probe for be leveling do I still use the z endstop? or does the ir probe take its place?

Thanks, I have seen wiring diagrams but never knew what was series or parallel.

OK, so series would be connecting the 2 stepper motors together into one connection? sorry I am new to printer electronics and such.

I am going to be building a new Cartesian style machine and I happen to have a duet 0.85. I was wondering if I can connect 2 z motors to the z axis port? I would have to join the two motors to 1 lead, now I know each motor will be 2 amps each and from what I read the z axis port can only handle 2 amps at a time. Is this correct? can I convert one of the extruder ports to a secondary z axis? I am using DC42s firmware / config. Also can the ir sensor be used for bed leveling?

Thanks in advance.
