I had to downgrade firmware

gjh · Posted at 2019-4-30 10:34:13

In pursuit of getting the probe function to work on my DDSC V1.1, I upgraded the firmware from 2016-x-x-73-NOR (sorry didn't record the full date) to 2019-03-20-107-NOR only to eventually discover that the problem was with parameter #223.
However, with the new firmware installed, system behaviour became very erratic, making a mess of simple carving.
In desperation, I downgraded to the oldest version I could find - 2016-06-10-80-NOR.
Now it's all working and I'm a happy camper once more!

Is there a point where firmware becomes incompatible with V1.1 hardware?

Palavan, It might be the voltage to the controller is too close to threshhold, I had this same problem using a laptop brick at 18V 4A, when I moved to a 24V 2A power supply the problem went away.

Hi gjh,
I did a survey on fb about whether the system is stable after the upgrade, https://www.facebook.com/groups/ ... k/2817905121559974/,
I did not see information similar to you, you can upgrade the latest firmware, try again.

Hi Ytliu,
Did you get any useful information from the set of numbers produced in #7?

Hi everyone, I had a problem. During cutting, the controller periodically freezes, makes a long sound and everything goes dead.
what could be the problem?

Thank you, you use the old version first, I will check the reasons for incompatibility.

OK - needed a couple of tries to get it loaded...

1219, 2, 1, 2016, 422, ffff

Version displays 2019-04-28-108-NOR

I haven't tested operation with this installed. I'm inclined to go back to what I know works.

This set of numbers.

I didn't see anything different.
What should I be looking for?
