I thought speed was a matter of whether use or not a32 bit mother board. But recently I heard somebody to say that it is a restriction of Marlin.

You need good input shaping for higher speed printing.

But here is an example he posted of a 14:12 min benchy on Marlin with his latest FT-MOTION code, and unlike more extreme speed benchy it still looks like a benchy! . (his hotend is now his limit)

I have two "expanders" which'll add +2 or +3 slots, so more than enough (if you can find/buy them or the PCB-files for DIY).]]> VDX Reprappers Wed, 24 Sep 2025 17:22:48 -0400 https://reprap.org/forum/read.php?4,897151,897219#msg-897219 https://reprap.org/forum/read.php?4,897151,897219#msg-897219 It seems that RADDS is a good option.
I am just wondering if I can use one of the slots for one more motor in z axis instead of another extruder.
Is it possible?]]> Henrique Reprappers Wed, 24 Sep 2025 15:19:37 -0400 https://reprap.org/forum/read.php?4,897151,897218#msg-897218 https://reprap.org/forum/read.php?4,897151,897218#msg-897218 VDX Reprappers Tue, 23 Sep 2025 11:05:49 -0400 https://reprap.org/forum/read.php?4,897151,897217#msg-897217 https://reprap.org/forum/read.php?4,897151,897217#msg-897217 What hardware do you recommend with RADDS and Arduino Due?

Many klipper users are under the delusion that Marlin is slower. This is not true,

You do need faster controller CPU. In klipper its a raspberry pi doing the heavy work, in Marlin you need a 32 bit board]]> Dust Reprappers Mon, 01 Sep 2025 00:22:39 -0400 https://reprap.org/forum/read.php?4,897151,897151#msg-897151 https://reprap.org/forum/read.php?4,897151,897151#msg-897151 But recently I heard somebody to say that it is a restriction of Marlin.
