No. My touch sensing board doesn't have hardware filtering. But does it matter? Because... as i said: even with a completely disconnected touch sensor and the holder disabled in the menu my UniSolder behaves that weird. So: why should the touch sensor output matter, if the touch sensing pcb isn't even connected while the problem occurs ;) ?

New firmware version published.

New:
- 1/8 power (JBC Nano now works even better) - shows "ACE" or "DCE" on main screen when in use
- Tip-change support

(...)
I have some problems with that version. All of my cartridges seem to stuck at holder temp. They all heat up to the selected holder temperature (250°C) and stay there... no matter what. I switched through the preset temps (280°C/300°C/350°C)... but nothing changes. I set the "Holder" in the menu from "On" to "Off" -> no change. I even disconnected the holder -> still: no change -> always 250°C.

I changed the holder temp in the menu and the cartridges are heating up according to that setting. Entering sleep mode works too though (cooling the cartridge down to the selected temperature after the selected time). But it seems like with the latest firmware my Unisolder ALWAYS thinks the iron is in the holder - even with a disconnected AND disabled holder :o .

here is the culprit of all problems:

Strange  :o ! I use the same simple old touch sensing board 'DinikS' and 'minkok' came up with a couple of years ago. I just rerouted some traces and moved some components a tiny bit in order to be able to mount it with two screws:

It is still connected to my UniSolder. But as i said: it works fine with the latest firmware.

Thx @sparkybg. Sadly i've had the changes reversed. My UniSolder now works fine again. I will carefully redo the connections later and definitely test your latest firmware after that (but at first i have to catch some rest since i work in the night shift and haven't slept for almost 20 hours  :(  )...

Since you wrote it in red: are there some critical changes to the bootloader?

I did that for pin 53 and 54. For the connection between pin 8 and 28 i did the soldering at work... used a microscope... a JBC station with a C105 cartridge... and some fine kynar wire. I did lots of mods like this in the past and checked multiple times for shorts and the pin count. So i don't know what went wrong...

For "tip change" function:
1. MCU pin 54 (OLED D/C) must be connected to MCU pin 53 - this is how MCU detects new function
2. MCU pin 8 (NAP) must be connected to MCU pin 28 - this routes the SLEEP signal to one of the available ADC inputs
Probably another stupid question by me:
Is it really just a matter of connecting the according pins of the PIC32MX564F128H with each other in order to support the "tip change" function with future firmware revisions on the old front pcb?

I'm just asking because pin 53 is labled LEDf/GND according to the schematics...

Do you have plans on testing the temperature of STD40P8F6AGs too? Just asking because STMicroelectronics sells 'em themselves and even offers an option to order a small number of parts as a free sample for hardware developers  ;) ...
