Thanks alot

thanks alot.

Thanks alot.
I understand it. Basically, the actual speed is set by the slicer and we include a limit for that speed so that the speed does not exceed that value. it's true?
And the following 4 numbers (300,300,5,25) mean for X, Y, Z and extruder?
And in addition to the extruder, this maximum speed should be defined for other triple axes (X,Y,Z) as well (Basically, here it is meant to limit the speed of the motors for the other three axes)?
Thank you very much for your help. That’s very kind.

Hello Sir. How are you?
Sir do you know what is "max feedrate" in marlin? how these “max federate” numbers are calculated?

I checked the Marlin examples folder and checked different models of printers and each of them included unique settings for “.And because of the uniqueness of these numbers in different printers, I guessed that this section must be very important because different printers use unique numbers.

I did a lot of searching on a topic in Hypercube printers and I couldn't find the answer for how to calculate max feedrate. I even asked this question in Facebook groups and I still haven't found the answer. also, On Marlin's website, there is not much information about this issue.

And forgive me for asking you so many questions during this time. I really search for topics first, and if the topic is unclear, I come and ask questions in forums and groups. thanks a lot for your help.

Unfortunately, malin website does not explain how the numbers should be calculated.
(And even the numbers in the Marlin firmware are not the same as the numbers in the Marlin manual.).

Hi sir. I saw on the internet that some people use a system called V-slot wheels instead of using rails and wagons in 3D printers.
Is it worth using this system in the axes of the 3D printer, or will the wheels break down and wear out very quickly? Can you please guide me regarding the friction and life of these wheels and if these wheels are good, which model should I get? (because I realized that these wheels have different materials)
Thanks alot

@deckingman
Thanks alot sir.
You have taught me many things during this time.
Thank you very much..

hello. sir i have a few more questions.
if we use BLTouch and connect it to Zmin, There is no need to use mechanical endstops for the zmin axix?
And usually 3 end-stops ( 2 mechanical for x and y and one bltouch for z min) are enough for xycore pritners?

I saw a video on YouTube saying that "Power less Recovery feature" in Marlin program may not work well for xycore printers. Thanks to your advice, I realized that if I use a 2 mm lead screw, the bed will not fall. The point is that if the bed does not fall, it is easy to use the power less recovery function in the Marlin program without any problem?

thanks.

Hi sir. thank you.
I think I have to read all the messages again. Since English is not my native language, I am translating my questions and answers with the help of Google. And because in some places Google does not do this translation well, I may not understand some sentences well.
