I’m just curious about the routine the printer goes through evry time before starting a print job.
On my Creality Hi, the nozzle and the bed heat up, the gantry goes to the top and does some checks then comes down again, dances around the bed a bit and stops. Then the nozzle cools down to 175deg and does a bit more of a dance, then cools down to 120deg then a bit more dancing then the nozzel heat goes off altogether, the gantry goes up t othe top again, comes down then stops. During this time there has been a couple of wasteful and unnecessary purges. Then the nozzle heats up again and finally the print starts.
And it does this routine for EVERY print. Take forever. It shoild n’t take anymore than a minute to do a bed level check. Why all the filament purging and powering down th nozzle for no apparent reason?
I am facing the exact same behaviour. Several heat rises and heat drops, poop purges, bed mesh, dual Z cals, etc. Wondering if all of these are required every single time a print is initiated. I would appreciate e.g. a macro for a user to periodically update the leveling mesh and other microadjustment issues, but not forcefully executing all prep/tests for every print.
The printer is on 1.1.0.60 firmware but it had almost identical behaviour with the originally installed firmware which was 1.1.0.48. I am using Orca to slice and upload via WiFi, using the default and untouched settings that Orca included when selecting the Creality Hi.
As a sidenote, I can appreciate safeguarding and foolproofing the printer prep procedure as to ensure perfect results for someone that rarely uses the printer and would most likely benefit from all these to be executed every time. But, noone printing 3-5+ items per day need these for every print, nor can waste 10 mins per print. I believe there should somehow be an internal setting, within the printer menu, that would allow for a user to skip the extra prep and testing procedures if so decided and execute only the bare minimum; e.g. dual Z calibration, Z offset check, 1 poop purge, or similar obligatory tests, and then start printing immediatelly.
I performed a reference test print where the print itself was ~12 mins but the preperation added an extra 10 mins, resulting to ~23 minutes total. I attach the Fluidd console output of the whole process for your reference. Lines in bold red are mine just to point out the major timestamps.
Until some solution is given from Creality, hopefully with a future firmware, can anyone shed some light on what is required and what can be skipped, prefferably with advise on what needs to be altered in the Orca “Machine start G-code” to minimise these prep/test times? Or even better, can anyone that has already solved this issue, share their Orca “Machine start G-code” that gives the least possible prep delay?
If you use Creality Print instead of Orca you can turn off the print calibration. there is not a lot of difference between the two these days and after several runs at Orca myself I realised I was gaining nothing and loosing a lot so why bother
I cannot dissagree with your proposal, but, I have been using Orca for years and for several brands of printers so, it makes a lot more sense for me to learn and use the same slicer interface for all my printers. It is mostly for practicality reasons and having a single workflow with all my printers.
Could you report the two delays from when the file is sent for printing until the printer actually starts the print itself; meaning, one with calibarion activated, and one without calibration.
Or, even better, if possible with Creality Print, I would be greatful if you could you post here the “Machine start G-code” for these two scenarios as given from within Creality Print itself?
With Calibration off the main gain is NO mesh leveling so if you deduct the time taken for that process that would be the gain in time. Also you will find Creality Print almost identical to Orca just a few less bells and whistles which I find makes it simpler to use. Why don’t you give it a try you can always delete it later.
