Ormerod IDEX Now that I have added IDEX (independent dual X carriage) support to RRF, I am wondering whether I can convert my dual-extrusion Ormerod to IDEX. I am thinking along these lines: - Use a modified version of DaveK's aluminium X arm, with a second X motor mounted on the opposite side and a little higher or lower than the first. One of the motors would have to be held in place by 3 screws instead of 4. - Two X belts, one above the other. - Modify the printed parts that join the X-rod and X-arm together at each end, to increase the spacing between them and make room for the extra belt. - Two different variants of the X carriage, one to engage with each belt without fouling the other. - A microswitch mounted at the end of the X arm, for homing the second carriage. Does anyone have any suggestions for how to improve on this scheme? https://reprap.org/forum/read.php?340,716056,716056#msg-716056 Tue, 13 Oct 2026 01:08:37 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?340,716056,719057#msg-719057 Re: Ormerod IDEX https://reprap.org/forum/read.php?340,716056,719057#msg-719057
Knowing that IDEX support is now in your firmware is really great news!

How about putting the extruders somewhere else and having a second rod on the other side?
Thus it might even be possible to keep the lenght and position of the first rod and more important
the size of the X-arm.

I guess i have to complete my other printer design to be ready to change my Ormerod to IDEX.
But my near fiasco with my dual head print conversion keeps me a little reluctant...

Best regards

Not really - you could also place the extra motor on the same side, behind the original (in the -X direction), a little higher or lower, to the keep the center of mass (whats left of it) over the threaded rod..

..or place it vertical on top of the original and use a couple of extra pulleys to direct the belt lower and parallel with the original

BTW, your Duet and PanelDue firmware is running beautifully, thank you!
