X and Z axis's not working - sparkness - 10-09-2019 Hi there, just received my Touch DRO for glass scales board, powered up , connecting to blue tooth, testing the axis's and X and Z are not working- one digit flickers when i move the encoder. works fine for the Y and W axis. put the board under the microscope and I see nothing out of place. the encoder is TTL output , just testing on the bench, have clean power in, getting 5.00 V out on the encoder pins and 3.27 on the 3.3v rail, am I doing something wrong? RE: X and Z axis's not working - sparkness - 10-09-2019 Well, I was testing with a rotary encoder. that works fine on Y and W axis's , I tested with a linear scale and it works on all axis's, will have to check further into the rotary encoder as it may need pull up resistors. RE: X and Z axis's not working - Briney Eye - 10-09-2019 If it's a standard 30mm rotary encoder with open collector outputs and you want it to be the equivalent of one with "voltage" output, you will need 2k pull-ups. The only difference between the two types is that they put the 2k pull-ups in the voltage-output encoders. RE: X and Z axis's not working - sparkness - 10-09-2019 added some 10k resistors - now working |
