Me? 😀

Nice plans, but for me, it doesn't work, if I select any file, with or without IS, it frozes and goes to BSOD. Dump here

RE:

I am impressed! Especially considering I forgot to swap my nozzle from 0.6 to 0.4.

I have never seen my Mini move so quickly. No ringing on this print either.

RE: 5.1.0-alpha1 Firmware for Original Prusa MINI/MINI+ with Input Shaper and Prusa Connect!

Oh Exciting,

Can't wait to give this a go........

I was just watching a print thinking that I wish the Mini could move faster like the MK4 & Bambu Labs with input shaping.

Now if this works well I will not feel like I'm missing out on anything.

It's Magic!!!

RE: 5.1.0-alpha1 Firmware for Original Prusa MINI/MINI+ with Input Shaper and Prusa Connect!

I was impressed before I put the right 0.4 nozzle on, now I'm very impressed. For a 17 minute Benchy this is pretty amazing.

Although the seams need a little work...

Can I use this if I have a Revo hotend on my mini ?

RE: 5.1.0-alpha1 Firmware for Original Prusa MINI/MINI+ with Input Shaper and Prusa Connect!

After installing the firmware my hot end would just bang until "error Homing" if you have this happen to you , POWER OFF the entire mini via switch (not reset) and turn back on . It will home fine 1 time, then back to error. 

So Turn Off , Hit Print and you get 1 home and print works . after that print you need to do the whole power off thing again.

Thanks ! Did you have to do anything beyond updating the firmware ? calibration etc ?

RE:

I'm currently testing this, and the time reduction is quite impressive. It's really great to see Prusa not forgetting about this little machine. I've been eagerly awaiting news like this since the MK4. I wondered if there was a possibility to implement something similar on the Mini, as they shared a lot in common 😋 

RE: 5.1.0-alpha1 Firmware for Original Prusa MINI/MINI+ with Input Shaper and Prusa Connect!

I got successful print off the 5.1.0-alpha1 (sliced with the new Mini Alpha profile from PrusaSlice 2.6.1) before I'm stuck with a failed to home x axis error (bangs the hotend into the right repeatedly).  After it beeps and shows the error screen/QRCode, I can click the button and it reboots.  Took a hard power cycle (toggled unit off, removed power for 1 minute, reinserted power, turned unit back on) before I could at least get the filament unloaded.

The error links to https://prusa.io/12304 (but that only takes you to the Prusa3D homepage for now, I presume that error hasn't been officially added yet)
There's an additional code below that reads O0H8ABOS

Wasn't able to do much more afterwards.  I'll attempt to troubleshoot some more, but a simple test print using a filament swatch with test added via PrusaSlicer turned out fairly decent, and half the time (17 minutes vs 34 minutes prior to the Alpha firmware).

RE: 5.1.0-alpha1 Firmware for Original Prusa MINI/MINI+ with Input Shaper and Prusa Connect!

My post is still waiting moderation for the work around I found . Power off your printer with the switch , waif 10 sec power it on . you can now home 1 TIME, and then the cycle starts over again. 

so I Power off , power on , hit print = homes and prints just fine . after Print you have to power cycle again. 

Hope they fix it , I have 14 minis but I only tried the update on 1 of them . 

RE:

For those with homing issue: tighten up your x axis belt, that helped me.

I wonder why some are getting the homing crash yet others not - i need to wait till they bring back Octoprint compatibility
