Anyone tried to make a 3D Printer controller?

Mon Sep 14, 2015 4:18 pm

Just did the math and saw that it could be possible to make a controller with atleast 3axis, 2 extruder, fans, 2 thermistors and 6 buttons (min, max). And from the sketch size it could also fit marlin onto a Maple Mini. Only thing would be a custom board with the pins. Did anyone tried this already? If not i’d take that as a side project

I’m designing a board around a VET MCU and can have 8 steppers 6 fets, 4 thermistors, 2 sdcards, LCD, and have pins to spare.

Should work with either.

I do not think flash size should be a problem for Marlin at this point but for sure the black F4 VET has more SRAM.

I do not like the voltage regulator in it, and don’t like the microUSB either.

But I really like the tiny form factor, and that can be unplugged for programming, testing, or reuse on anything else.

It is a nice mini F4 VET board. I only looked at black F4 VET, but the mini version is even better. I am going to order one also.

I agree, that board has a good form factor and good price. I posted about it in a different thread yesterday, where someone wants to make a Due form factor board, to show that its probably pointless as they cant compete on price etc.

I dont have one of those, but I will order one today.

Re: Regulator etc

You can put a duplicate reg on your board, and depending on the internal USB wiring on the board, you can probably put a duplicate USB connector on your board

That’s great news! Unfortunately, my cat decided to learn how chew-able electronics are and stole from the table my only bluepill (note to self: next time buy more than one) so I have to wait until the new one arrives… yeah, that’s my luck…

you might want to check the feline’s teeth, also if any bits are missing from the BluePill. I’ll leave further investigation to you, note X-Ray of the cat in the UK costs £70, the further bit to remove the 2″ needle and its attached thread adds another £250.

Roger, the USB pins (PA10 and 11 or whichever they are) are indeed in the headers, so I have thought on that.
5V and 3.3V are also available, so I could add a usb connector, then power the regulator on board with 5V, or add a different regulator and feed the board just with 3V3.
The only pins sadly not available in the headers are the analog refs and grounds, and the Resest pin, so you reset you have no choice but to use the board button. It’s a really nice little board.
The voltage regulator is not too good, and there is no diode protection on VBUS, those are the major drawbacks I have found.

I guess someone’s cat ate a needle :lol:

@spon!

Ah.. Its a single layer PCB. That explains things. Are you making the board yourself?

Re: Straps

I’m not sure how this is accomplished, the only workaround I can see is to add some 0 ohm resistors to your schematic, for the connections you know need to have straps, when choose a footprint of a resistor which is big enough to bridge the gap.

then in production, just fit a insulated copper wire.

As a matter of interest, I will see what the KiCad work-around is for that…

Yes, I still working on a controller based on STM32F103C8T6, (cartesian and scara robot arm) but, I can’t work i2c on this chip, so i beginning to avoid this microcontroller and migrate to another

Fri Sep 29, 2017 7:25 pm

[rsc – Fri Sep 29, 2017 7:03 pm] –
but, I can’t work i2c on this chip

What kind of issues ?
Do you have some PullUps on the I2C bus ?

Sun Oct 01, 2017 2:59 pm

doubt i2c would be any obstacle on STM32F103, but i’d think 3d printing would likely be rather demanding on both memory (sram) and processing power especially with the ‘simplier’ stepper drivers that basically offers only step and dir. if one uses st’s L6470 motor drivers
viewtopic.php?f=19&t=572&start=270#p34962
it may well be rather feasible as that use SPI reducing the pin count and pretty much offloads the mcu doing most of that motor control within the L6470
the downside would be that L6470 is rather pricy, one would be somewhat limited in terms of how much ‘control’ one have as much of the motor control work is delegated to the L6470.

I’m developing the scara for 3d printer using STM32F103C8T6, now can draw with trapezoidal movement profile (as grbl) further would need PID and ADC for 3d printing but it is at the limit of memory occuped 64% flash and 33% ram, code was reduced when use C only and some register but still need to optimize more (you can see bluepill

)

old video without trapezoidal movement profile (obviously without precition)
