Can someone please provide some assistance. I recently built a cnc router I am using ramps 1.4 arduino mega. The issue I am having is I was using belts and changed it to threaded rods I am pretty sure I have my steps entered correctly however all zxis will move just fine by hand and if I only move 1mm at a time but if i try to move more than 1mm at a time the steppers make noises and look like they try to move but they wont move like it is stuck but it cant be stuck as it moves 1mm at a time just fine. Does anyone know what might be causing this. I am still very new at the firmware/programing side just as a heads up
If your wiring is OK (per Peter's post above) check your maximum speed and acceleration settings - chances are that they will need to be much lower for leadscrews vs belts. Small moves may be OK because they never reach full speed.
Wiring is good. I will play with the speed and acceleration settings today and see what happens. Any idea around what number I should put in there for those? Also Thanks for the help
your max speeds are too high. default zsfo rlLEAD machines are [14:30:46] [ $$ ] $110=2500.000 ;X-axis maximum rate, mm/min [14:30:46] [ $$ ] $111=2500.000 ;Y-axis maximum rate, mm/min [14:30:46] [ $$ ] $112=2500.000 ;Z-axis maximum rate, mm/min [14:30:46] [ $$ ] $120=150.000 ;X-axis acceleration, mm/sec^2 [14:30:46] [ $$ ] $121=150.000 ;Y-axis acceleration, mm/sec^2 [14:30:46] [ $$ ] $122=150.000 ;Z-axis acceleration, mm/sec^2 should get you moving, then you can try higher speeds or higher accelerations (probably more useful)
I attached a notepad version of the configuration h file with feed rate and acceleration settings I tried from other people who are trying to help. If someone sees where my mistake is please let me know as I have played with the settings several times and seems to be no change. I dont think this would be an issue but I am not using endstops as i will just be manually setting my zero before each use, which is how i did it wit my previous machine that used belts and didnt have any issues
Sorry, I saw 'CNC router' and thought you would be running GRBL on the Mega. I haven't got the foggiest about Marlin.
I haven't made it that far in this journey yet lol. However I have parts and plans for a bigger machine with nema 23 motors that I will have to use GRBL so I will have to learn that as well. And I wouldn't be against using that on this machine as well I just like the fact that I can run it on an SD card instead of having to have a computer hooked up to the machine the whole time
