I think M7 is overkill. No FDM printer can move that fast to actually take advantage of M7's speed. Unless you intend to get some encoders and get into closed-loop servo control. I'm not sure about Nucleo headers being "Arduino compatible", you would still have to edit pin definitions files in firmware, so... I actually got a "Discovery" board because processor is in a bigger package=more pins (by +Mikie - Controllers
Yeah, I saw that after I posted. Panucatt isn't really forthcoming with the details, and what little is there needs digging. I was under the impression they introduced Bigfoot format to improve cooling, and it does "solve" that. Well, "improve" is a better word. These small drivers need to be cooled from below, through the substrate, and Bigfoot being bigger provides more copper surface on the boby +Mikie - Controllers
Victor_pv, have you gotten anywhere further with your board? I've bought myself a STM32F407 discovery board today, planning to build a RAMPS-like board for it. Seeing how you clearly know more than me, plus you already have a real board... Is there any other news, a schematic perhaps? What STM board did you plan to plug into it? Looking at the 3 sets of pin headers, Discovery boards don't fit iby +Mikie - Controllers
AHA! I'll give it a go this afternoon and report back. Thanks, Dust. P.S. He does advertise his board every time, doesn't he? Edit: No need to wait, I did it. That was it, now the menu selection is inverted and clearly visible. Thanks a lot, Dust.by +Mikie - Firmware - Marlin
In Marlin 1.1.8 selected menu item is marked only by 2 thin lines above and below, at least on my Anet A6. Anyone know if there is some sort of editable setting to make the selected menu item appear in negative? To be more obvious, especially looking from the side of the LCD?by +Mikie - Firmware - Marlin
So Traumflug, no plans to design a "Gen8" board, split in two like the old RAMPS+Mega, using ESP32 or one of the STM32F4 "Discovery" or "Nucleo" boards and a freshly-designed RAMPS-like to suit it? If made larger (say 150*100), it could be made easily DIY-friendly? STM even has a complete 3D printer board with Marlin ported to it for less than $120. Lots of people know how to mess with Marlin, Iby +Mikie - Next Wave Electronics Working Group
Traumflug, have you thought or maybe planned to change the Gen7 board into a simple expansion board like the old RAMPS, and have a choice of several NPC processors on a DIP adapter board? I understand the advantage and desire to have a controller DIY-possible, but nobody was putting Megas together in the old days. Maybe more desirable to have the "shield" separate from the processor? I see aby +Mikie - Next Wave Electronics Working Group
Hmm... Maybe time to ping Traumflug to blackm... PERSUADE him into switching to a better processor and add a 5th motor driver. Chinese can make a LQFP to DIL adapter board for a processor, so the basic "shield" would still be DIY-workable, something like the old RAMPS/Mega combo? Problem solved Now where did I put my persuasion bat...?by +Mikie - Next Wave Electronics Working Group
As above, with respect to new genuine open source community-supported 32bit controllers? The only board I see represented here seems to be Gen7, and it too seems to be dead-ish. Having a single extruder may have something to do with it. Even the ancient RAMPS had provision for two, and I thought we were supposed to go forward and not backward? RAMPS-FD and Smart RAMPS seem to be dead-end, andby +Mikie - Next Wave Electronics Working Group
Jaycar has a few different kinds, but for more choice (and higher prices) Farnell - or as it is now known Element14. You can search and place order online, then pick it up from their trade counter. Delivery is around 13 bucks, usually overnight.by +Mikie - RAMPS Electronics
