I am struggling with time to close MCU crashes. The errors only happen after printing for 8 plus hours on small parts.

The issues started after I switched from a cable chain and wire harness to a fysetc H36 tool head board on canbus.

To try and resolve the issue I have upgraded from a CB1 to a CB4 8GB ram with no significant change. Looking over my klippy logs, I noticed that all the Print stall errors happen immediately after a max speed change in the G-code from Orca. I also see that I have no errors on the canbus. I did find that disabling adaptive pressure advance helped, and allow the prints to go longer before it crashed.

Im having issues with random mcu shutdowns with error "timer to close" during prints. I think the error is happening around the same time, around 3 hours into a print but im still testing.

The issue is not every print but the ones that are failing are statues with lots of short extrusions.

I just finished upgrading my printer and installing a fysetc h36 toolhead and setting it up the canbus.

Im looking to see if anyone has a way to stress test the buffer quickly without having to run a 4 extrusion.

My printer:

MCU m8p + cb1

Toolhead fysetc h36

Box turtle with AFC light board.

I just got a suprise raise from work and im not sure what to do with it. My first instinct is to split it beyween my debts and saving for a new car. My current car is a lease and I have to turn it in in January.

My second thought is to use it to increase my grocery budget a bit and put the rest into savings till my emergency fund has 1 months expenses.

Details:

Current budget

Rent/utilities/phone : $2026

Loans + credit cards payment: $1400

Medical debt: $250

Groceries: $280

Savings: $300

Home goods/fun: $100

Savings:

Emergency fund : $1100

New car fund: $1100

My current takehome is $3746 per month and my wife adds another $650 towards bills.

My raise is going to be about $550 per month after taxes.
