Start print in center of bed FT-5

"RELATIONSHIP TO THE START AND STOP POINTS OF THE AXIS"???
im a bit confused here , I am building a very modified FT5 for this board . I imagine that my endstops are low?

dc42

Low endstops = endstops near the X=0 and Y=0 end of the bed or gantry

High endstops = endstops near the X = maximum and Y = maximum end of the bed

You can have one high end and one low end if need be. Once you know which end your endstops are and the X and Y coordinates at which they trigger, configtool will generate the correct homing files and the correct M208 commands in config.g for you.

shojidoug

its not the board but 3 d geometry in general. the point where xyz all meet is numbered 0 0 0 so your location start point could be
X POSITION = X-0 ,Y POSITION = Y-0 ,Z POSITION = Z-0
I am assuming. after much reading and no direct answer from any source that 0 is low and thus if i have my end stop at a 0 position it is a low end switch, even though my bed is all the way up, its starting point is Z-0

@shojidoug:

Thank you for answering
I have entered the dimensions in the slicers.
thank you for the advice and the config you will post. If i have to i will move my end stops x would be no problem. but i would have to tear down the gantry and hot end to reverse.
the 713maker gantry upgrade kit i have installed was not engineered to be flipped so if i can avoid it i will.

Ahh it's not stock then?

Where does your hotend home to? You have a picture?

looking from the front to the rear Y right x rear z of course up
please forgive the mess, I haven't reached the tidy up point and if i could figure out hoe to post a pic i would.

For posting images you can upload to https://postimage.io and it will give you a direct link. You then add the image in your post using the image option in the options above.

ohh , it was sounding much harder than what I was thinking , all mine should be low if I understand your post correctly.
thanks !

ok got it to work with Slic3R Thank you every one

ok got it to work with Slic3R Thank you every one

Can you post yout config so i can look and see whats going on with the ft5 . I would like to see what you did to fix your issue to gwt a better understanding . Thanks

This has not been tuned and I only have it working on Slic3R , have not tried the native files that come with the firm ware.
Also they have an IR probe for it that is inexpensive might want to research that because its very accurate.

Thank you very much , what IR sensor are you talking bout ? I dont remeber seeing it at filastruder. Do you know of a usa distributor?(EDIT : i must have missed it at filastruder . I see it now . I was expecting something to look a bit different. )

I home the hotend to back right of the printer (as standard for the FT-5) I set X & Y switch to high end so it's parked around 305. That gives me a front left corner of the bed X0 Y0, front right of Y0 X305 and back left of X0 Y305. In S3D i just tick flip Y build plate so every STL i load is usually the correct orientation ready to print
