[FR] XYZPrinting Da Vinci 1.0

[kubark42]

Description

A number of people have an XYZPrinting Da Vinci printer, and while it has a Repetier fork bouncing around, it's quite old now and the Marlin firmware would be a very nice upgrade.

The Da Vinci is a nicely build enclosed printer which uses a 32-bit Atmel ATSAM3X8E microcontroller and A4988ET stepper motor drivers.

Configuration Details

• Manufacturer: XYZPrinting
• Model: Da Vinci 1.0
• Motherboard: 1.0
• Repetier fork: https://github.com/luc-github/Repetier-Firmware-4-Davinci

Additional Information

• Pinout: https://github.com/luc-github/Repetier-Firmware-4-Davinci/blob/master/pinout.xlsx
• WINSTAR 16x4 documentation: https://github.com/luc-github/Repetier-Firmware-4-Davinci/blob/master/lcd-4x16-bn.pdf
• Extruder and bed temperature vs ADC reading: https://github.com/luc-github/Repetier-Firmware-4-Davinci/blob/master/bed-extruder-tables.xlsx

I'd be very happy to take point on this if someone can walk me through the process of bringing up a new board. I did this a lot at Tau Labs, so am familiar with what it takes in general. I lack the specifics of how to do this with Marlin.

[ellensp]

Its not just a board... The LCD is also non standard. a WINSTAR 16x4 char display. and 5 buttons, but how is it all connected? 24pin ribbon cable...

[kubark42]

I feel like the LCD is a nice-to-have, but certainly not a requirement. If there's already support in Marlin for this style of driver and it's only the pins which change, then cool. Otherwise, arguably it's not worth adding code bloat for a non-standard screen. The real payoff for the firmware upgrade is all the cool Marlin features.

Great question about how it's all connected. I did some digging in the Repetier fork and found several interesting documents. I linked them to my top post. It has uC pinouts, LCD documentation, etc...

The LCD is connected with a thin ribbon cable, as show in the pic below:

[ellensp]

Well the first thing in my view is to examine the script apply_patches.py, work out what it does

It updates .platformio/packages/framework-arduino-sam with specifics for this board,

It replaces .platformio/packages/framework-arduino-sam/cores/arduino/USB/USBCore.cpp with the file Repetier-Firmware-4-Davinci/PIOPatches/USBCore.cpp and .platformio/packages/framework-arduino-sam/variants/arduino_due_x/variant.cpp with the file Repetier-Firmware-4-Davinci/PIOPatches/variant.cpp

Mostly this is adding pins 92-99,109 -114 and 115 .. 125

which leaves the change to this line, what does it do? Do we need to create a variant, or can it be done some other way.

Modofied < { PIOB, PIO_PB11A_UOTGID, <- this one is changed ID_PIOB, PIO_PERIPH_A, PIO_DEFAULT, PIN_ATTR_DIGITAL, NO_ADC, NO_ADC, NOT_ON_PWM,

Original.

NOT_ON_TIMER }, // ID - VBOF

And then there is the "USB PATCH to avoid dead loop" to consider.

I suspect will need to create our own marlin board variant to support this board.

[kubark42]

So would it be fair to say this is not as straightforward as appropriately configuring Configuration.h and Configuration_adv.h?

If so, that's disappointing, and arguably not worthwhile until there's a larger pool of people who'd benefit.

[ellensp]

Needs a board variant created, need a new board pins.h file added, needs a new type of LCD added. Then you can add a Configuration.h and Configuration_adv.h that uses these features

[kubark42]

Needs a board variant created, need a new board pins.h file added, needs a new type of LCD added. Then you can add a Configuration.h and Configuration_adv.h that uses these features

So, here's my understanding:

• New variant
  • Where are the variants kept? I have perused https://github.com/MarlinFirmware/Marlin/tree/2.0.x/Marlin/src and nothing jumps out at me.
• New pins.h
  • This seems easy and straightforward: Clone a ATSAM3X8E board, e.g. https://github.com/MarlinFirmware/Marlin/blob/2.0.x/Marlin/src/pins/sam/pins_ARCHIM1.h, and point toward the Da Vinci board pins.
• LCD
  • Ignore LCD for the time being, as it's not a priority and is not required
• Add Configuration.h and Configuration_adv.h.
  • This seems like it requires some amount of specialized familiarity. If I get things as far as this, is it easy to find someone to guide me at that point?

[ellensp]

I have created a Marlin that complies for this board. It creates the Variant It has a boards pins.h file LCD is not supported at all It has a rudimentary Configuration files

I have no way to test any of this.

Test each function with extreme caution!

It may not boot, it may set all heaters to max and try and burn you, all the axes are probably backward. Pins could be all wrong. Assume nothing!

You probably should not do this is you cannot restore the machine to its current state.

NB the thermistor type are wrong... at default of 1.

Its a start https://github.com/ellensp/Marlin/tree/Da_Vinci_1.0

[ellensp]

You can see whats been changed in https://github.com/ellensp/Marlin/commit/9b5c44aa68427ea807c8cd57774dfbf8a3883942

[kubark42]

Thanks! I'm sincerely appreciative of this, I hadn't at all expected such an awesome boost this early in the project.

I've got the board pulled out of the machine and sitting on my desk, so it should be easy to test.

So that I know how to start massaging these values myself, how did you determine what changes to make? I notice that some tweaks, such as https://github.com/ellensp/Marlin/commit/9b5c44aa68427ea807c8cd57774dfbf8a3883942#diff-bb298d18dac4268225a7a53a5ad24844472530bdc63f6a98a2ba8d8158b75080R1375, seem very precise.

[ellensp]

Information was extracted from https://github.com/luc-github/Repetier-Firmware-4-Davinci/blob/master/src/ArduinoDUE/Repetier/Configuration.h where possible

[kubark42]

Ahhhh, makes sense. I'm guessing you've done this before so you knew how to translate from Repetier settings to Marlin. 😄

Okay, gonna get right on this today and see how far I can get. Hopefully because there's already Repetier on it I can easily use the bootloader to switch to Marlin.

[ellensp]

Its sort of readable, but no I've have very little to do with Repetier. I just read through it, picking out what I could see translated easily to marlin

[kubark42]

Gotcha.

BTW, hats off to whoever created Auto Build Marlin. I just discovered it and it was everything I could have wanted. The only, admittedly very minor, challenge was realizing that I needed to check-out the Da_Vinci_1.0 branch in order to have ABM see the correct build files. Once on the correct branch, ABM downloaded all the correct reqs and built everything flawlessly. Now on to the next step!

[kubark42]

GRUMBLE, GRUMBLE, first hiccup is that the board won't power on with a pure USB connection. The upshot is that I have to bring it back to my lab, where the rest of the printer is, before I can power it on and test any further.

[kubark42]

On the plus side, it flashed okay.

On the negative side, well, it didn't exactly brick the board since the bootloader still works, but once past the bootloader stage the USB port disappears. I haven't started to look into it yet, but I suspect that Marlin firmware uses a set of alternative serial port pins from the ones used on the board.

[kubark42]

@ellensp, do you think the serial port issue could be because https://github.com/ellensp/Marlin/commit/9b5c44aa68427ea807c8cd57774dfbf8a3883942#diff-bb298d18dac4268225a7a53a5ad24844472530bdc63f6a98a2ba8d8158b75080R105 sets the SERIAL_PORT to -1?

[ellensp]

when the usb port is directly connected to the Controller cpu, SERIAL_PORT should be -1 If its using a uart with a usb to serial chip, then its ports 0-3, but I don't see any usb-serial chips on your board...not on the picture above.

Trace the D-,D+ pins from usb port, where do they go?

On the due its these pins D- pin 38 DHSDM D+ pin 37 DHSDP

[kubark42]

https://github.com/ellensp/Marlin/commit/9b5c44aa68427ea807c8cd57774dfbf8a3883942#diff-1cc05ed1b31b129e4b57e0d9f1da1ad3bf9aa261f05c5f09c84f1b4473ffdd8dR124 shows that the serial port is configured as PA8/PA9, which is the same as in the pinout.xls file.

I'll trace the pins and report back to be sure.

[kubark42]

Scoped out and confirmed that D- goes to 38 and D+ to pin 37.

Could this be a crystal configuration issue? The Davinci board uses a 12.000H40 crystal, which is the same 12MHz xtal as on the Archim I have here.

https://github.com/ellensp/Marlin/blob/9b5c44aa68427ea807c8cd57774dfbf8a3883942/buildroot/share/PlatformIO/variants/MARLIN_ARCHIM/variant.h shows 12MHz, but I can't find the equivalent for this board setting.

[ellensp]

Due also has 12mhz crystal on xin,xout

[kubark42]

Hmmm..., I am too unfamiliar with the ATSAM to have many other ideas why the chip might have crashed or the serial port might be misconfigured.

I'm thinking it might make sense to shotgun this with the variants of DUE boards and see if anything boots up properly. With a bit of luck, it would give us a known good scaffold upon which to progress.

Thoughts?

[TokoloshiMedicine]

Complete Noob here - But I am following this thread anxiously...This would be such a great mod for this printer. I have the AiO version though, with the scanner built in. Could anyone help me backup the firmware that is on the MCU in case i brick mine. Before i try any mods

[thinkyhead]

I'm in the midst of trying to get Marlin working on the Duet 2 Maestro with the ARMv4 ATSAM4S8C. My brain is falling out.

[TokoloshiMedicine]

Haha I hear you, well good luck with that,keep up the great work

[yoroboticscolombia]

HI guys, just to ask if the marlin for the davinci was created, thanks.

[chepo92]

Hi everyone, what about creating a draft PR gathering all the work?, I think we are missing just a few things

[thinkyhead]

I have faith in the community to figure it out!

[chepo92]

Hey @thinkyhead, you mentioned you have some work done for the duet 2, do you have that in a public repo?
