Okay. If we use the Signal Access Module to inject the TTL signals to control the step motor. What size of a glitch can the stepper motor chip of the base or the Nanoscope controller handle?

Thank you for your contribution but we still could not fix it neither we understand the origin of the problem. Your third point matches it more than the others. I quickly try to describe the problem. We encountered a very strange problem with our base. Since we tried to control the stepper motor by our matlab and basic written programs the motor does

Hi I am very interested in buying a STM Head Converter for our Multimode III system. For further details please contact me.

Dear Peter Thank you for your helpful answer. Unfortunately, it seems that the stepper motor is not turning anymore by our software & hardware control and by the Nanoscope software either. Although, it moves by the manual switch. We measured the signals coming from both Nanoscope control and our home-built control and it seems that the TTL signal

Hi all.... We have a problem with our Multimode 3 v. 5.30r3.sr3. Although the stepper motor moves by the manual switch it is not moving anymore by controlling it with the Nanoscope software. We hear some noise in the stm base but the screw is not turning. Did anybody have a similar experience?

Dear Peter For our Multimode III we observed a pattern like this for a step size of 26nm: Step 1: 0 1 1 1 Step 2: 0 0 1 1 Step 3: 1 0 1 1 Step 4: 1 0 0 1 Step 5: 1 1 0 1 Step 6: 1 1 0 0 Step 7: 1 1 1 0 Step 8:0 1 1 0 Which is different of the one you posted. Anyway, I suppose the sequence of the pattern does not matter, is that right?

Hi I am trying to access the step motor with an auxiliary controller. By connecting an oscilloscope to the control signals (A,B,C and D) we saw TTL patterns which seems to carry the information about direction and step length. Thus I would like to ask you for the TTL patterns of step size 26nm and 998nm up and down? Additionally, I would like to ask
