@NexxCat thanks man! you have been amazing. Ill keep googling to see if I can get anything. Hopefully someone else can maybe assist.

@Phaedrux Firmware Version: 2.05.1 (2020-02-09b1)

haha fingers crossed! Thanks for the help, Ill report back as soon as I get a chance to test

@Phaedrux thanks I can confirm updating the firmware fixed the issue

@Phaedrux the reason I havent done this is because, well as you can see im not the greatest at firmware. My understanding is that most of the code for the config etc has changed? If I upload this wont it break my existing?

@Phaedrux sorry I missed you asking for the firmware.
The video was only 3 seconds because the forum will only allow a 4mb upload.

Firmware is 2.02RC5

S5 V2.mp4

@Phaedrux @dc42
Sorry guys I thought maybe a video to show this is the easiest.

As you can see, when you hit resume, the nozzle drops from the correct height to resume, to x0 y0 z0 and then starts moving to go back to the resume point. This almost always knocks the print off the bed... How do I correct that?

G1 R1 X0 Y0 Z5 F6000 ; go to 5mm above position of the last print move
G1 R1 X0 Y0 Z0 ; go back to the last print move
M83 ; relative extruder moves
G1 E2 F3600 ; extrude 2mm of filament

Ahh ok I see what you are saying. So the issue and why I set the maxima to 467 was simple. Past that you run out of room to move. If I change the maxima to 500, anything past the 467 causes the rails to hit the end of the rail and cant move past. So the 467 is the physical limit of it.

let me try explain it this way.

X0 Y0 should be the front left of my bed. I have made a mark 10mm in from each side given that the bed is actually 510 by 510.

My X and Y coordinates are actually X5 Y6 when I position the nozzle over this point on the bed

My X endstop on the X actually hits at X5 so it recording a position of X5 would make it 10 which is correct mathematically, but will mean that everything actually prints 5mm to the left.

Frankly Im just lost on the Y

@Phaedrux well thats what I thought... but the problem is that if I make the endstop 0 and tell it to move to Y250 Im well off the center of the bed.
I am understanding that I have the 500mm in movement, but if I had to try and print a 500x500 block for arguements sake, Id be well off the bed. How do I get the firmware or the slicer understand the positioning correctly?

Hi Everyone,
Im an absolute amature when it comes to firmware, so please excuse me but I am trying to learn. Im having an issue with positioning the print head and endstops, and Im assuming I need to put in some type of offset. My printer is a CR10 S5 (cartisian with 510x510 bed size, print area 500x500). I bought a linear rail kit from 3Dfused, but Im having a serious issue with the bed positioning.

If I home the Y axis and take this position as 0. Then mark the actual center of the bed with a marker, the printer needs to be at Y287 to actually be center of the bed. The issue with doing this means that if I try to move the full length of the bed (Y500) i run out of space at Y467 .
The actual rail lengths are 650mm.

At first I thought maybe the motor esteps were off, but Ive tried printing as big as 360x340 as a test and dimensionally the print is perfect. So I dont believe its the esteps and more has to do with how the firmware is recording the endstop and bed positioning.

Any suggestions on how I fix this so that I can actually use the full extent of my bed?

@Phaedrux I really dont think its the start code haha... but for safety sake here it is:
