So I have this bench topmill that I converted to cnc. using an arduino uno to controll the system and I am using UGS to send the files. everything is set up and was going soomthly until I hit this little bump in the road. It is my understanding that when I initiate the homing sequence “$H,” the machine is suppose to move to the limit switches until it make contact with them and then pull off 1 mm. When I initiate the homing sequence the mahince moves about 5 mm in one direction on all 3 axes then stops moving. If I turn on hard limits in grbl, the UGS immediately alarms out and says I need to restart to unlock.
Heres is the equipment currently on the machine:
6 limit switches (NC setup)
3 x nema 23 high torque motors
24v 15 amp power supply
Universal g code sender
Any help would be greatly appreciated and please remember I am a novice with this so my understanding of scertain things is a little limited. Also if this post doesn’t go here, then I apalogize.
