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?

I think they should be compatible.

The system behavior you said is very erratic, and I want to know the specific phenomenon. Is the movement stopped, the display is still, like freezing?

The task was to carve some numbers. It seemed to start ok but at a consistent point first the x-axis trips on position error then the y- axis trips.
I don't have the drive faults wired to stop the program, so it carries on, but x and y don't move, of course.
On another job - cut a single slot: it cut the x & y dimension ok but didn't reach proper depth when it finished. At the end when it attempted to return to the work zero (G54), it didn't quite make it - even though the drives did not trip - but there was a terrible noise that, in my experience, is caused by an oscillation due to too high acceleration.

I want to know some specific information about your controller, and the programs in the attachment will display them on the screen. thank you.

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

This set of numbers.

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.

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

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?

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