Firmaware 3.12.2 Revo
Hello,
This version 3.12.2. does not work with Revo either... Error again.
By the way, how does the printer know that there is a Revo?
RE: Firmaware 3.12.2 Revo
did you try to follow the steps from:
https://github.com/prusa3d/Prusa-Firmware/issues/3636#issuecomment-1451733927
i had a print running for 20+ min after calibration.
There is also the option to disable Thermal Model.
https://help.prusa3d.com/article/thermal-model-calibration_382488
and no it is not possible for the printer to know exactly wich hotend is installed.
RE: Firmaware 3.12.2 Revo
Firmware definitely does NOT work with Revo.

Sorry, I didn't sign up to be a beta tester, and don't plan to run a 27 step/2 day test for Prusa. Maybe Prusa needs to buy a Revo and test it themselves. Hey, I bet E3D would even give Prusa one to try for free.
And my guess "Thermal Compensation" is a solution for a problem that doesn't even exist.
RE: Firmaware 3.12.2 Revo
It was not supposed to work with the Revo; they said from the beginning that it didn't. I am not sure why people expect the factory firmware to support their modified printers.
RE: Firmaware 3.12.2 Revo
Kinda strange because 3.11 works with it beautifully, so 3.12 BROKE support for a very popular hotend introduced, what a year ago. If Prusa had some smarts they would have made the Revo standard on all their printers. The Revo is probably the biggest improvement to come to the MK3 in 5 years. Prusa is not exactly winning in the hardware game, if you haven't noticed.

RE: Firmaware 3.12.2 Revo
I've just tried firmware 3.12.2 and can't get it to calibrate. It fails on the refining C est. stage. Yeah, it is improved but is not fixed.

RE: Firmaware 3.12.2 Revo
The Revo has also had a lot of teething issues/failures with the heater units which they are hopefully getting past. Given the issues with them I have read about here and elsewhere (predating and having nothing to do with the current incompatibility with the latest firmware), I don't blame Prusa a bit for sticking with what is known to work (V6) for their printers and kits. The bottom line is the firmware never "supported" your modification of adding a Revo hot end to your printer, it just happened to work with it. That's a big difference. When the new firmware came out they told everyone that it doesn't currently work with the Revo, which is more warning than most manufacturers would give to users who have modified their product. Prusa doesn't appear to sell the Revo as an accessory on their site, and I don't think they have endorsed it.
Either way you still have plenty of good firmware options for your modified printer. The simplest is to go back to the prior firmware which was known to work. You could even configure your own generic Marlin installation, or switch to RepRap Firmware or Klipper, and then at that point who cares what Prusa does with their firmware?

RE: Firmaware 3.12.2 Revo
Revo works very well and better than V6
I have a printer farm with 50 printers with Revo and since no more problems
You have words that are not consistent with an obtuse vision
RE: Firmaware 3.12.2 Revo
I think the Revo is great and I put one in the Voron that I am building. I have done so, despite the numerous threads here and elsewhere concerning failures of the heater cores. From what I can tell E3D had some technical issues when they scaled up from making prototype, test, and sample units to full production. Which is a common occurrence will all types of products. There have been fewer complaints about this lately, so it seems like they are getting a handle on it, and in any event they seem to have been more than willing to replace all the bad ones with no questions asked.
I am glad that you haven't had any issues with yours. That doesn't change the fact that plenty of people had problems with theirs, and posted about it here and elsewhere. I'm also probably going to change both of my Prusas over to Revo at some point too. I wouldn't be if I thought that there was anything fundamentally wrong with it, as opposed to having typical new product teething issues.

RE: Firmaware 3.12.2 Revo
Firmaware 3.12.2 will not work out of the box with Revo. The default TM values are for V6 that's why I posted the link to the issue with the required steps for TM cal. (you need serial console or a gcode file)
I think some of these commands need to be executed for the TM cal to work with Revo. It is possible that the TM cal from the display does not work at all with Revo (hardcoded values for V6).
I don't think Revo has better print quality than V6 its mainly easier to work with, on the contrary since you can get some really awesome nozzles for V6 if you are willing to spend some money.
@allen8355 don't Beta test if you don't wan't to, but Prusa has no obligation to support modified Printers. Thermal Model calibration is a safety feature so it has its benefits. And I don't think MK3 will ever get Revo as the default hotend its more expensive and not as reliable yet, I think at the earliest it would be with a MK4 with 32bit board and some other small tweaks.
You can also just do steps 10-15 from the guide without logging (and hope it works) and don't contribute for the improvement of the firmware, but then you shouldn't complain if the Firmware doesn't work with a heavily modified printer.

Hello,
I'm not talking about better print quality, but simpler maintenance, we've been using revo for 1 year now
RE:
They (E3D) said in a early video on youtube, the nozzles would cost a few $/ € more than a V6 nozzle (approx. 12 $).
Meanwhile the price is close to 30 € in Germany for one sinlgle plain brass nozzle !!
Then after some months they added, you should do a first layer calibration after nozzle swap
although the nozzles are all said to be manufactured to the same length. This was also not mentioned in the beginning.
Then there were often problems with bad thermistors in the heater cores... throw away the entire heater because it is one integrated unit...
Then there was no hardened nozzle available for a long time.
Hardened diamond coated nozzle came out for 60 € - was available for some days. Now again not available until mid of May ...
I guess, i will not buy a Revo any more.
You are restricted to the nozzles E3D wants to offer and can deliver.
The pricing of the nozzles seems to me like the "E3D-way" of creating a kind of a expensive subscription system.
RE: Firmaware 3.12.2 Revo
I don't understand after more than 4000 hours of printing no problem in ABS and if it is necessary a small cleaning and it is good. I don't understand your problems...
RE:
Supply and Demand has always been an issue with new products, but as soon as someone starts to clone their own version, price will go down. That’s just the way supply and demand works. And the cost to you compared to me in the US it's going be different because of the change rate from the company that's selling from a different country. That's just something companies can't control.
I had the same issue with bad thermistors in the heater cores also, but after changing the extruder body the issue went away. I found that every time I change the nozzle the heatsink would spin a little, I was trying to ensure the nozzle was seated properly and it would bend the wires on the heater core. I think it would short out the heater core. The heater core does have an aluminum wire management to prevent this but it's too thin and would bend also. After changing the extruder body, all my issues went away with changing nozzles and bad thermistors and heater cores. E3D did change out their thermistor and heater core the new one has a blue label and older models have a white label.

RE: Firmaware 3.12.2 Revo
All I can say is thanks for linking this @matteo. This was a life saver. I updated and started wondering why my printer could no longer print. Followed the steps you linked and within 30 minutes I was ready to start printing again.

RE: Firmaware 3.12.2 Revo
E3D & PRUSA released the Firmware 3.13.0 Revo for MK3S+ (a specific version, with different TM).
I installed on my MK3S+ and I was able to print.
It requires a FACTORY RESET (all data) just after flashing, otherwise the FW insists to use the old E3DV6 values stored in EEPROM and nothing works.
After flashing, perform the Wizard setup that will setup all the PID values.
RE: Firmaware 3.12.2 Revo
Well, I tried it, didn't work for me it's still It fails on the refining C est. I flashed it and then it did a reset and then I did a factory reset and then I did a factory set and deleted all my data and still had the same issue. After going through the self-test, it would error when it was testing the nozzle for temperature never completing the self-test, I probably could have printed something but every time I shut it off and started back up it wanted me to do C Est. I reflashed with 3.11 had no issue during self-test back up in printing, without any prompts saying that I had to calibrate something and making me intervene to start G code.

lmfao
RE: Firmaware 3.12.2 Revo
Hello, after Thermal model calibration, do we need to perform a PID tuning?
I am using E3DREVO_fw_MK3_3_13_1_6876.hex
