Hello all, I searched the forum for discussion on this topic but didn't find any relevant. I am 'attempting' to upgrade Marlin firmware (1.0) on a Hictop Duale 3 board to latest release available. Besides trying to identify which pins should be used for X2 and E1, I am struggling with the configuration_adv. I believe DUAL_X_CARRIAGE is the best option for my case. I have dual X drivers and dual E drivers. I have had to manually enter many of the variables for X2. I also can't seem to get control through "Motion" menu to move or adjust the X2. I have been looking through anything I can find to try to answer these questions on my own. I'm reaching out to see if anyone has had any experience with this 'unmarked' board, or if someone can point me to some documentation. Thank you for your time. https://reprap.org/forum/read.php?415,849481,849481#msg-849481 Fri, 13 Mar 2026 20:01:57 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?415,849481,850931#msg-850931 https://reprap.org/forum/read.php?415,849481,850931#msg-850931

I have requested the Original Firmware from Hictop for the HICTOP DUALE 3 IDEX]]> Roberts_Clif Firmware - Marlin Sat, 06 Apr 2019 15:25:45 -0400 https://reprap.org/forum/read.php?415,849481,850761#msg-850761 https://reprap.org/forum/read.php?415,849481,850761#msg-850761
Though Have never seen any firmware on any Printer from Hictop past 3DP18.
Firmware for the HICTOP DUALE 3, is not even seen in the section to download firmware.
Is there a Location in the documentation for firmware download where one can take a look.

If you have opened the controller box could you show an Image of the controller.
Is this your video.

However, I warn you that, although dual x used to work in old versions of Marlin, the latest one does not work properly. I’m having problems with the x carriages crashing into each other on tool change.

I use Repetier to control the printer. Provided you’ve set the extrudes to 2 then repetier recognises that you have two print heads. You switch between them by entering T0 or T1 at the command prompt in repetier or by selecting the extruded in the temperature control. When I work out what’s broken and fix it, I’ll post a setup guide.]]> MotoBarsteward Firmware - Marlin Mon, 25 Mar 2019 16:25:50 -0400 https://reprap.org/forum/read.php?415,849481,849487#msg-849487 https://reprap.org/forum/read.php?415,849481,849487#msg-849487 2 Z Motors with 1 Steppe Driver and 1 Min_Endstop
