The smoothie bootloader sits in the first 16K of flash and is responsible for reading and flashing the firmware.bin from the sdcard. As a worst case scenario, you would want to be familiar with flashing the bootloader just in case something goes horribly wrong and making sure you have access to those pins on your board. Note that it is the Smoothieware firmware which presents the SDCard as a exby sdavi - Controllers
I also forgot to mention that for RRF you also need to update some of the coreDUET to use the samd arduino core. At a very minimum the startup parts which setup the interrupt handlers, etc etc, and any thing else that is device specific.by sdavi - Firmware - experimental, borrowed, and future
Very recently, i got RRF v1.20 running on my Azteeg X5 mini (LPC1768 based board that used to run smoothieware) just for fun, so I have been though this. I've never heard of scons before, the fact it uses python is enough to make me avoid it so I cant help with that. I'm sure adding a new profile (or editing i.e. the radds one) to the eclipse project would be simple enough. However, I ended up jby sdavi - Firmware - experimental, borrowed, and future
Perhaps what I should have said is adding a line about testing for, or looking out for, the pizeo connection if its behaving oddly. I did have the red piezo wire (own one i drilled out) to the +ve so the idea of the piezo being in "backwards" wasn't even a consideration, especially since it "appears" to work when tapping it. Your comment from July is what I eventually found and is something whatby sdavi - General
Quotecoredump PS: ALSO, I watched the 6 videos about installing and configuring and there is very important information there that isn't on the manual, for example I was totally unaware that the piezo polarity made any difference. Also better information on the measure procedure would be great Yes, the polarity does need a special mention in the docs. It's one of those difficult things to trackby sdavi - General
QuoteDjDemonD As for other firmware marlin seems like we can get some tweaks in there. Smoothie are open to adding something if I can get someone to fork it and make changes. Initial attempt at adding a pause (dwell) before probing to smoothie. I don't actually have a pizeo yet, but testing on my delta with a long delay of 2 seconds and it does work with G30, G31 (delta_grid) and G32 (delta_caliby sdavi - General
QuoteLeav One more detail I need to share: the hotend heater had one end wired to the (+) of the heater outputs on the board and the other end was wired directly to ground (not the (-) outout of the transistor on the board). Most boards usually switch the GND side and not VCC, so the board sounds like its working as expected. Hook up the other wire to the - instead of directly to GND and it shouby sdavi - Controllers
Good to hear its all working now Just read through those comments on github, interesting they say the angle corrections are incompatible with delta-grid. I don't recall seeing that anywhere in the documentation.by sdavi - Controllers
Yes, its strange to close so quickly. At the very least you'd expect them to wait to see the logs they requested. I never had any luck with tower correction angles in smoothie, as soon as I used them it would make things a lot worse. Out of interest, I just downloaded the latest firmware to put on my Azteeg X5 mini. The calibration ran though without a hitch, M500 no problems, M501 prints currby sdavi - Controllers
Quotenebbian I've submitted an issue for this: Your so called "bogus" config (sorry, but I had to laugh when I read that) has currentcontrol_module_enable defined twice, the 2nd one is right at the bottom of the file is incorrectly set to true.

QuoteParabolic Okay, I moved my probe closer - by half. Its now 11.5mm to the right and 41mm in front of my hotend. so this would be: leveling-strategy.rectangular-grid.probe_offsets 11.5,41,0 # Optional probe offsets from the nozzle or tool head ??

QuoteDjDemonD leveling-strategy.rectangular-grid.probe_offsets 0,0,0 # Optional probe offsets from the nozzle or tool head I always get quite confused whether to use positive or negative numbers. Offsets should be the probes location relative from the nozzle. So, in the X, probe located left of the nozzle would be negative and right would be positive.

Very briefly looking at the endstop code in smoothie, looks like the compensation is disabled, then it does the homing, then re-enable compensation when its finished. I guess that could be an issue when homing to min which sets z=0, then it applies some compensation +/- value in Z for that XY point, which could be the reason? Perhaps if you home to min as you already have, then move up say 5mm oby sdavi - Controllers
According to smoothie zprobe docs, the pre-built binaries doesn't contain the rectangular grid compensation and you need to compile the firmware from git. Looks like the 3-point leveling is built into the pre-built binaries. Also, G32 would start the probing and not G31.by sdavi - Controllers

No worries, there is quite a lot of info to learn and sometimes finding it on the wiki can be a bit hard, especially if you don't know the right terminology to search for. Based on the specs of the motor (1.5 amps), it should be able to be driven directly from the RAMPS. The DRV8825 specs say they will drive up to 1.5A without any heatsink and active cooling so you could run the motor close toby sdavi - Australia, Melbourne RUG
The reprap wiki has some good info on Stepper Motors and also Stepper Wiring. As you have probably noticed, your motors have 6 wires and the drivers on the ramps only has 4.

You can use a 2D plot and a rotate extrude. I found a 2D graphing library on thingiverse to quickly come up with this (source code attached): Just have to tweak the equation to get the shape you want. You could also import a dxf and use the rotate_extrude as well.by sdavi - Let's design something! (I've got an idea ...)

Have you had a look at Polycaprolactone (PCL)? Its listed as being biodegradable, non-toxic and melting temp of 60 deg C.

I use the 2093EL from bunnings and the only time its ever stuck to the part was when the nozzle was set too close to the bed.

The full graphic LCD actually connects to a separate adapter board via 2 ribbon cables (labeled as EXP1 and EXP2 in the schematics), and the adapter board then plugs into the RAMPS board. The adapter board schematic can be found here reprap.org.
