I am configuring my CoreXY D-Bot
I have soldered the connections to have gamma slave to epsilon - now I have doubled my stepper motors to be the Z axis
The document says to remove gamma_step_pin, gamma_dir_pin, gamma_en_pin
I figure these entries must now be entered in the epsilon positions
My config file has only the lone #epsilon_current entry
I require the epsilon_step_pin, epsilon_dir_pin, epsilon_en_pin entries - as they do not appear in my config file
Imported from wikidot
there are no epsilon step/dir pins, for M4 and M5 you are looking at removing/not adding extruder modules
When I remove:
gamma_step_pin
gamma_dir_pin
gamma_en_pin
What is used to drive the 2 stepper motors?
Am I missing the obvious?
Could you post the complete config file set for a “coreXY”
I’m pretty confused and not sure I understand what you want to do, or if there is even any kind of problem in the first place.
What are you trying to do, and how exactly is it not working ?
Sorry,
The first time I flashed all axis moved - I had problems with the endstops not stopping but running on
Realized my board was nor being reconized so my config changes were only being saved to my file on the hard drive
Purchased another Micro card and downloaded the firmware file and config file
Started to change my config to meet my needs
My Z axis is buzzing and not moving now
That is why I am asking to view a complete config file using a coreXY and double stepper motor set up
Hope that helps explain my request better
You don’t need to see a configuration file, that’s not how configuring smoothie works. If you are asking for a config file, it essentially means you are trying to skip reading the documentation ( which has all you need, tens of thousands of users have gotten their machines to work with just the docs ), and that’s not a good idea, both for quality of understanding, and for safety reasons.
I’m still very confused as to what is going on, you were talking about jumpering drivers, then pin config, and now an axis not moving, all of which don’t seem very related to each other ( and have presumably nothing to do with the machine being corexy either ).
Can we concentrate on one issue at a time ? Your Z axis isn’t working : can you try another motor on that axis, and try that motor on another axis and report the results please ? Thanks.
Thanks for your patience
I am using Simplify3d as my interface
I cut and pasted a new unconfigured config file on to the sd card and flashed it
The Z axis moves as it should
The X axis when pressed to move left moves 45 degrees back and to the right
The X axis when pressed to move right moves 45 degrees front to the left
The Y axis when pressed to move back moves 45 degrees back to the left
The Y axis when pressed to move front moves 45 degrees front to the right
End stops when I enter M119 all 3 read 1 - when I press each stop it reads 0
This is all with no changes to the config file
The end stops I understand need a ! added
I have changed anything to tell the board this is a coreXY setup
Am I over complicating this - I almost have the doc memorized
I added the arm_solution corexy and set to true
This did not change the motion moves still as above
I added the ! to the 3 _min_endstop and flashed the card - endstops are triggering by hand properly
I figured out my biggest mistake - copy and past between the hard drive and sd card and an older config file and over complicating the whole process
My XYZ are all moving in the right direction
End stops are triggering as they are suppose to open and closed
When I home X good - Y and Z start to home in the wrong direction -
alpha_min_endstop 1.24^!
beta_min_endstop 1.26^!
gamma_min_endstop 1.28^!
When I remove the ! from Y and Z they only move about 5mm in the right direction
I am so close - What could I be doing wrong?
The ! inverts the signal, not the direction of the axis.
To invert the direction of the axis you need to invert the step pin for that axis.
I have downloaded new config files and another new sd card
My beta and gamma lines are:
beta_step_pin 2.1!
beta_dir_pin 0.11!
gamma_step_pin 2.2!
gamma_dir_pin 0.20!
All 3 end stops trigger when pressed
The X axis triggers and moves as it is suppose to
The Y and Z axis move as they should except when I try to home they travel in the opposite direction
I added the ! character to the step pin but no difference
