The smoothieboard is fantastic, and I have been making good use of it. I recently re-built a custom corexy printer and everything went swimmingly - until I went to home the axes. The motors are all wired in an identical manner, and I did not change the config file from when I shut it down to when I rebuilt it. The only change is that I put updated firmware on the Smoothieboard 5X (pulled from github on 6/19/2016).
My issue is that the X axis moves in the wrong direction. I have tried inverting the connectors on the board, and inverting the direction pin definitions in the config file (with all conceivable combinations) for both alpha and beta (my ‘x’ and ‘y’ motors). I am having flashbacks to working with the early Printrboards that had this sort of problem on the Y axis — any thoughts?
Config file for alpha and beta:
# Stepper module pins ( ports, and pin numbers, appending "!" to the number will invert a pin )
alpha_step_pin 2.0 # Pin for alpha stepper step signal
alpha_dir_pin 0.5 # Pin for alpha stepper direction
alpha_en_pin 0.4 # Pin for alpha enable pin
alpha_current 1.5 # X stepper motor current
alpha_max_rate 30000.0 # mm/min
beta_step_pin 2.1 # Pin for beta stepper step signal
beta_dir_pin 0.11 # Pin for beta stepper direction
beta_en_pin 0.10 # Pin for beta enable
beta_current 1.5 # Y stepper motor current
beta_max_rate 30000.0 # mm/min
Second issue - I have the servo module enabled, and I am able to get a partial response from the servo, but it is not working the way it should. If I pass M280 S10 to the board, the servo moves about 25 degrees from vertical (vertical would be S5). Any additional M280 commands will not produce a response. If I issue M281 I can hear the motor control release, and I can manually move the servo back to vertical, where it will respond to M280 S10 and move about 25 degrees again, but it will not respond to any other commands. I checked and double checked the power, and an arduino can move it no problem, so it has to be the signal. Maybe my pwm signal is not at the right period? The motor is an analog HD1501 MG power servo.
Config file for servo:
switch.servo.enable true #
switch.servo.input_on_command M280 # M280 S7.5 would be midway
switch.servo.input_off_command M281 # same as M280 S0 0% duty cycle, effectively off
switch.servo.output_pin 3.25 # must be a PWM capable pin
switch.servo.output_type hwpwm # H/W pwm output settable with S parameter in the input_on_comand
#switch.servo.pwm_period_ms 20 # set period to 20ms (50Hz) default is 50Hz
On issue 1 : does M119 report the endstops to work correctly ? Can we see your endstop config ? ( it’s generally a good idea to post the full config, with the collapse tags the interface mentions )
On issue 2 : You know Smoothie uses 0-100 not 0-255, correct ?
Thanks for the quick response, unfortunately I am traveling this week so I am not by my smoothie or the PC that has the config - I’ll see if I can’t get the Mrs to email it so I can post it.
To answer your inquiries,1) yes - M119 reports endstops just fine - in fact I can home the machine and hit the end stop for x manually (as it is moving away from it) and it stops as if it is home - again will post the config when I get it or when I get home later this week.
2) Yes — the reason I posted is that I was using this servo setup previously and it worked just fine (S5 = vertical, S10 = 90 degrees+) — when I embedded the M280 command in gcode previously I had to put a G4 pause in to let the servo finish, but in the past I was able to issue single M280 commands that worked just fine.
Thanks again, I’ll post the config on here next time.
Finally got back to the shop and figured I would get to the bottom of this. Grabbed the new edge firmware at github Smoothieware/FirmwareBin - loaded on the SD card per usual to flash the board. Revisited several older versions of config that I had used on this same setup to make sure I hadn’t missed something — now the Y axis is reversed (X homes correctly to min, Y tries to home to max, and manual control is reversed).
The servo is still unresponsive save the M280 S10 command, which still moves much less than it should and then is unresposive. Checked again, and arduino can move the servo the full range with the same data connection. I also tried a whole new data wire from 3.25 to the servo and got the same result.

Can you try starting from zero using the very latest firmware, and very latest configuration, editing only one config option at a time, and testing it each time ?
Sure - apologies for muddying the water — just flashed new firmware, and grabbed a new config file. I only changed the items that relate to the steppers and the endstops (and removed the links as my karma is too low to post them). Tried this:
Wired the motors in an identical manner to what had previously worked - alpha, gamma and epsilon are oriented in the same manner (looking at the board from above, stepper connections on the top, BYGR from a NEMA17), beta is reversed (RGYB from the NEMA17). In this configuration, X direction moves fine, M119 shows ends stops are as expected, Z direction is fine. Y is reversed. Homing correctly goes to X zero, Y attempts to go to max (away from the endstop at Y=0) and will stop if I manually trip the Y endstop
Wired the motors so that are all in the same connection to the smoothie alpha, beta, gamma and epsilon are all the same (BYGR from a NEMA 17). In this configuration, X direction moves fine, M119 shows ends stops are as expected, Z direction is fine and homes fine. X manual commands now move the print head in an opposite Y direction, Y manual commands give correct X axis movements. Homing has the print head attempt to go to Y max, then correctly goes to X min.
At this point I am thinking i could just swap the connections for the Y motor A coil and it should work, but I am perplexed why the identical mechanical setup is now behaving differently.

Hi arthurwolf - just a followup - thank you for your advice, I was able to get the corexy movement working properly by running through all the combinations of motor connections and orientations (of course the one that worked was the last one I tried):
The servo module is now working just fine as well. I should’ve spent more time troubleshooting on my own before posting, Thank you for your advice, and for supporting those of us that like the smoothy.
