RepRapFirmware 3.0 port for LPC1768/9 based boards

Thanks for your information.

Ok. I believe the firmware would also have to be modified as I think the arrays for the pins only accept 5 inputs. Gloomyandy would have to confirm this.
What drivers is this designed for?
It should also work ok the SKR 1.4 as the EXP 1 and 2 ponputs are the same.

I'm a new bee to reprapfirmware, so i have some questions. Does reprapfirmware for skr support extension drivers? The output pin of wifi extension board which my firend designed is directly from lpc1768 digital io. The pin number is P1.18 to P1.23, and each output driver use 3 of them.

Looking at the other boards that are supported, none of them use pins from port 1 of the LPC.
I know for some features, only pins on port 0 and 2 can be used.
External drivers can be used, I'm just not sure whether the pins your friend has picked can be used to driver the drivers.
@gloomyandy needs to answer this one

Thank you very much, at least the wifi will work

I don't think there is any limitations on the pins the can be used for stepper drivers. However the current builds of RRF only support up 5 drivers, so if you want to use more you will need to modify the firmware and rebuild it

WOW! I'm very excited for your reply! Is there a plan to support 7 drivers in the future?

Is there a plan to support 7 drivers in the future? Thus we could use lpc1768 in more machines,eg voron2.4 ,toolchanger system...

Hello together,

I've just joined the club with RRF 3.1.1-6 running on the SKR 1.3 and 5x TMC2209 connected to Raspberry Pi 4. All the info here about HW config is pretty straightforward but there is always a but and that is for me the firmware settings.

My printer is delta kossel powered by 24V 20A power supply with 240 mm heatbed and single v6 extruder. There are 3 temperature sensors:

1. Semiter 104GT as heatbed sensor connected to TB pin
2. PT1000 with 1k resistor connected to TH0 pin
3. Semiter 104GT as an ambient sensor connected to TH1 pin

but there are just a 2 heater elements:

1. Anycubic heat Bed soldered as 24V one
2. Extruder powered by 50W 24V heating element

I believe that I have all the temperature sensors configured properly but there is something fishy in assigning the sensors to the corresponding heating element. I mainly struggl with the logic how to assign temperature sensor to the heating element and how to configure temperature sensor without heating element. Another issue is how to display the sensor values in web interface.

@jafido

You don't need to assign the bed as a tool
Add "M140 H0" after your M307 H0


For the other sensor, give it a name using an A"name" on the M380 for the sensor. Make sure you use S2 rather than S1 (as its sensor 2).
So assuming the last one is your extra sensor "M308 S2 P"TH1" Y"thermistor" A"Sensor" R4700 T100000 B4725 C7.06e-8 ; configure sensor 1 as thermistor on pin TH1"
The use the "+extra" next to the tools where the temperatures are shown as you can add the sensor to the chart there.
If you want it to always be displayed, then you need to add it to a dummy tool [forum.duet3d.com]

You also said you have 5 TMC209 but you've only mapped 4 of them. Whats the other one for?

thanks jay_s,

I haven't got from description "The first example informs the firmware that bed heater 0 (implied, because no P parameter is provided) uses heater 0." that M140 H0 command does the trick . My learning curve to be familiar with the RRF is not so steep as I would expect from youtube videos.

I've modified the config.g according to your suggestions but I am still not able to display the ambient sensor.

The 5th driver is currently not used but I plan to use it as a second extruder or for the moving RPI camera

thanks again Jay_s,

there was nothing but after few restarts the change was propagated. . This firmware is like from another world. It is completely different philosophy in comparison to the Marlin. Is there any chance that somebody has already designed the PCB for SBC and SKR v1.3/1.4? I wanna build some and it is a question whether to design it from the scratch or somebody has already made it.

MKS Sbase v1.3

I did everything just like here [github.com]

@kasper that error means that rrf is unable to talk to the esp8266 module. There are many possible reasons for this....
1. Wrong sort of WiFi module, or firmware not installed.
2. Wiring problems between the boards
3. Poor power supply to the module
4. Problems with the modification to the Sbase board
5. Probably a few others as well
It would probably help if you posted pictures of your WiFi module and close up pictures of the wiring to the module and the wiring on the board, please also include close ups of the modifications to the SBase board.

It seems to have done everything as in an article on GitHub

I take it you used the board.txt file from the wiki?

The only other issue I can see is that you're powering the wifi from 5v from the board into the 3.3v on the wifi board. The power should be connected to Vin on the wifi.

Power is connected to the Vin on Wi-Fi on Sbase to the 5v pin in the EXP-1 connector

Something strange going off here. It has picked up some of the board.txt settings (look at the SSP0.Pins values for instance), but it does not seem to have picked up the board type correctly. @kasper I would check very carefully that there are no odd characters around the line that contains "lpc.board = mkssbase_v1.3", I'd be tempted to delete that line and re-enter it.

Theres a typo on the wiki

Yes I've tried it once or twice )

It looks to me like you are connecting to at least one of P0_15, P0_16, P0_17 via the pins in EXP1, don't do this, use the pins on J7 (you are already doing this for two of the pins, but I can't tell from the photos which ones), you basically want all three of those connections to go to J7.

If you are still having problems please take some more pictures that show the connections to J7 and EXP1 more clearly and do the same for the ESP board. At the moment I can't really check what you have connected.
