I have a Makelangelo 3.2 and have downloaded and installed 7.10.0 software on Windows 10. I can’t find any instructions on how to calibrate and make a first print. I did find a “m4 calibration.pdf” in the zip file without any explanation. Btw, I’m in the US so if the measurements printed on the paper are meant to be accurate I’m not sure how to accomplish that using 8 1/2 X 11 inch paper. Resizing the print +10% does not seem to do it. Help please. How do I calibrate it and make a “hello world” equivalent first print?
8 1/2 x 11″ US letter size paper is the size used in the PDF. as long as your calibration printout is 1:1 with the original PDF it will be accurate. This video details the steps, and is linked from the page where you purchased the M3.2. It was just a link, which I have now upgraded to a an embedded video. Thanks for pointing out it could be better!
Does that help?
You are correct about pressing “set home” when at the home position.
From the home position when you Y-100, how far does it actually travel?
make sure you are using the right stepper motors,
The steppers Dan uses are 400 steps, if yours are 200 you will have to change things in the firmware.I had the same problem and when i changed the stepper value it worked fine.
I think its in the Config table in your firmware.
Cheers
Y-100 should move 10cm down, ~4″.
What happens when you send the message D2, what does it say? for a 20-tooth pulley it should say 12.7323954
There’s a log at the bottom of the app and below that a blank line to send advanced commands directly to the robot. Type D2 in that box and click “send” or hit enter.
Hey I tried D2 also on my bot and i get the same results..
D2 L1.27 R1.27
What does that mean if its meant to be 12.57/..
ALSO
when i do D1i get
D1
adjustPulleyDiameter dia=1.27
cir=3.99
SPT=3200.00
tps*1000=1.25
SD is addedWhy is the pulley size 1.27??
shouldnt it be 12.57
is this the error we are looking for
it’s supposed to be 1.27, i wrote it wrong.
I don’t initially see anything wrong. Normally if it goes the wrong distance it’s
– wrong machine size (seems ok)
– wrong pulley size (1.27 is good for 20 teeth)
– inverted motors (try settings > jog motor, in should go towards motor, out should go away from motor)
– failure to flip the DIP switches under the drivers. all switches should be in the DOWN position. DO NOT remove the drivers with power plugged in, you can permanently damage the drivers.and after that the issue is something exotic. Does that help?
So in my case
my machine size is 650,
Just to confirm it was measured from inside the 2 steppers and not the shafts.
and my board length is 1000mmhowever,
When ever and i mean WHEN EVER i move my axis around.. Left or right i get about 130mm but up and down i get half that distance..i know that i am using 200 stepper motors.. and i have adjusted for this in the code.. but otherwise my machine is identical to yours.. and the fact that he has a store bought one and having the same issues.. says there is a problem that we are clearly overlooking.
I don’t believe there’s anything physically wrong with the machine just yet, as we test all machines before shipping and you’ve shown all motors and servos have worked on command. I strongly believe there’s a software or configuration problem.
Of course I have a machine here of that model, so I’m going to re-run the code here, do a test drawing which I’ll post on instagram and link here, then get you exact settings from my machine after the test run.
Hey Dan,
How about my Bot? you seem to have given up on my thread that i posted…
I am having same issues as this guy with the drawing lines..The lengths are totally wrong..
Update: we are currently running our tests and should have real news a bit later today.
@fishingincairns I’m sorry if I haven’t been on top of everything. There’s a lot going on and I’m doing my best to keep all the juggling balls in the air at once. I hope when I solve this it fixes things for everyone?
So now we need to figure out what’s different between your machines and ours.
We downloaded the firmware and software from the website as a customer would.
We opened the firmware and made sure in configure.h that the following was set:#define MAKELANGELO_HARDWARE_VERSION 3 // If you have a makelangelo 3+
//#define MAKELANGELO_HARDWARE_VERSION 5 // If you have a makelangelo 5+(normally the // is on the first line)
Then we uploaded that firmware.
In the makelangelo-software,
we connected to the robot
we check that left in moved towards the left motor
we check that left in moved towards the right motor
we centered on the home position (~20cm from the top, i forget the exact measure) and clicked “set home”.
our board is 835 wide and 1220 tall. Our A2 paper was 190mm from the top of the board, so I lied to the machine and said the board was 974 tall (A2 height 594mm + 190*2) so that the paper would appear in the middle of the machine. I could have also moved the paper down to the center of 1220. I like fixing things in software when I can.
we ran a border test, which outlined our A2 paper minus our 10% paper margin.
we loaded thankyou.dxf with “optimize on load” selected. DXF loading will load all the lines in random order; optimize will sort them end-to-end to save a lot of wasted moves and drawing time.
we put in a black sharpie (wow, I don’t miss how annoying that is on the 3)
we hit start. drawing proceeded normally.

Hey Albert Jones,
I am glad your getting the help you need from Dan.. .i started a Thread on similar issues on the M5 that i built and it seems that he is ignoring it.I am going to try the M3 information on my M5 machine to see if it makes a difference.
