I don't how 4 pin handle is connected but in 5 pin handle you have 2 pins connected to ground (on the PCB).
Check here: https://www.aliexpress.com/item/32933941125.html?spm=a2g0o.productlist.0.0.25824e14MR1zrh&algo_pvid=d3e4c3f8-d6a4-42a3-ab41-69b8991642be&algo_exp_id=d3e4c3f8-d6a4-42a3-ab41-69b8991642be-59&pdp_ext_f=%7B%22sku_id%22%3A%2212000022941698495%22%7D
G and E (green and black line) are connected together on the PCB board (check bottom of the PCB where you can see G and E markings near the white connector).
I hope that helps you.

A discharged capacitor is seen by the output as temporary short circuit until it charges up. For maybe 10us, there'll be a short but tough current spike, easily exceeding 50-80Amps depending on the wire properties and how fast the mosfet is turned on.
As the frequency rises, so does the number of times it happens per second, beating the crap out of the transistor. Any square pulse of any frequency will cause this problem.
With AC, usually you send half waves, so the voltage will start at 0V and rise evently, the power is delivered in a much smoother way, there's no such sudden capacitor charge.
This fw uses 5Hz by default, if the pid and filtering are properly adjusted it works very well.

Strange, that's the correct firmware for that board. Anyone having else this issue?
Can you post the log from the programming tool? Try making a full wipe.
The guide to preserve the settings, where you skip erasing the last 2 sectors, is only for settings made by this firmware, so you can update to newer versions keeping everything.
But not for the original firmware, that one stores them in the eeprom, this custom fw doesn't make use of it, so they'll be preserved always.

In a 5 pin handle, the wiring is typically like this:
- Power
- NTC
- Shake
- Ground from power supply (Common for ntc, power, shake)
- Chassis earth (isolated from power supply ground)

I guess a 4-pin connector joins earth and gnd, like this:
- Power
- NTC
- Shake
- Ground from power supply + chassis earth

Quicko (Not Queeco) uses a 6-pin plug, it's  similar to the 5-pin, but with 2 ground wires, no NTC (in-board) and has a second sensor input for a different heater type, I guess for hakko 936 heaters, which use a PTC sensor.

Adapting the wiring isn't complicated, but you must check the connections in your board.

I've attached a log from another attempt about an hour ago, I've been performing a full wipe with each attempt and it seems to all go through just fine. It programs and verifies just fine both with this and the OFW I'm using.

Here's a copy of the log.

Is anyone running the latest fw in a Ksger v2.1 board?
