Does running a PID Autotune with an increased cycle count result in more accurate PID values?

I'm using the mriscoc firmware for Creality Ender 3 V2. The firmware has the option to run more PID Autotune cycles. The default is 5 cycles. Does running a PID Autotune with an increased cycle count result in more accurate PID values? For example…

Why is MPC better than PID for 3D printers, and (why) is it more useful for 'high-power heaters'?

The YouTube video 'PID vs MPC' from Mark Misin Engineering Ltd perfectly demonstrates that Model Predictive Temperature Control (MPC) is more powerful than Proportional-Integral-Derivative (PID). Marlin implemented MPC as described in Marlin's MPC…

How do I fix deformities when printing on my Ender 3 V2?

Being a newbie in 3D printing, I have some trouble with my prints. After removing wiggle room from the X axis and the bed, there are deformities even on simple prints. The first layer turns out okay-ish but there seems to be some stringing that…

Does a Creality Ender 3 V2 running mriscoc firmware require a micro SD card at all?

To my understanding, all settings including those that resulted from the Nozzle Auto MPC tuning and Bed PID tuning and the created UBL mesh are all stored I the EEPROM by the mriscoc Marlin firmware on a Creality Ender 3 V2. I'm asking because I…

Is it possible to read the state of a specific printer part from the firmware, such as the power of a stepper motor, LCD brightness, or fan speed RPM?

Is it possible to read the state of a specific printer part from Marlin-based firmware such as mriscoc, such as: the power (on or off) of a particular stepper motor; the brightness percentage of the LCD screen; fan speed of individual fans (in…

Is the BFPTouch interchangable with the BLTouch for mriscoc firmware without custom changes to Marlin?

I have two Creality Ender 3 V2 printers with a version 4.2.2 board. One printer has the official CRTouch, and one is nearly original without a probe. I found a similar product, a DIY project called BFPTouch, and I have almost all the parts needed to…

Is there a way to send a thumbnail to the printer LCD screen when printing over USB from OctoPrint?

I'm using Cura Thumbnails using a plugin in Cura 5.5. Also, I use the Marlin-based mriscoc firmware on a Creality Ender 3 V2 with OctoPrint using OctoPi on a Raspberry Pi 4. The firmware supposedly supports Thumbnail's preview when printed from an…

How to physically wire a (ADXL345) accelerometer for Input Shaping (Resonance Compensation) support on for a Ender 3 V2 printer?

I'm looking into Input Shaping (Resonance Compensation) to compensate for vibration on an Ender 3 V2. I found the "Official Creality G-Sensor ADXL345 Vibration Compensation Sensor for Sonic Pad 3D Printed Smart Pad" which I guess, unlike the name…

How does Adaptive Mesh Leveling (AML) actually work?

I recently started using the new mriscoc firmware for my Creality Ender 3 V2 and it is truly performing above expectations. Even considering that Jyers UI was already a step up from the original Creality firmware. I'm trying to understand how the…

Ender 3v2 nozzle plunging into bed after finishing mesh (only changed springs)

Yesterday I was printing just fine. Today I put the new springs that I bought from Amazon. Swapped them out, went to level things and my Z-offset was of course way off. I have the Ender3V2-422-BLTUBL-MPC-20230904.bin firmware from mriscoc I homed…

Aquila X3 small firmware does not flash to board

I'm using the MRiscoCProUI firmware on my Aquila X3 printer, but when I enable more features in the firmware, I'm unable to flash the printer. I already tried several options and independently of the ones chosen, when the firmware gets to around 230…

During a print, why must I continually adjust the Z offset to a more neagative number to keep the nozzle from air printing?

The nozzle is not clogged. After an adjustment, I get two to three good printed layers then the nozzle begins to lift away from the print. If I do not adjust the Z offset more negatively, then the print begins to go airborne in very small…

Uneven mesh after perfect auto tramming?

BLTouch enabled Ender 3 w/4.2.2 board running mriscoc's Professional firmware. How is it that the auto tramming can report the corners of the bed to be level, and then immediately afterwards it produces this mesh? What am I missing?

Why do two identical Creality Ender 3 V2 printers have a center that is 3 mm off from each other and 7 mm off expected and how to calibrate it?

When pushing the limits of the bed size (235x235 mm) for two Creality Ender 3 V2 printers running the same mriscoc firmware and the same config and upgrades. I noticed that despite using the same G-code for these two fairly identical printers…

How to successfully flash a DACAI LCD screen of a Creality Ender 3 V2?

I thought I had two identical Ender 3 V2 printers, the main board in both is v4.2.2 but it turns out they came with a different LCD screen. I flashed the firmware on both printers to mriscoc firmware and tried to also flash both LCD…
