Re: Wrong positioning when turning right

Hello Andrea, when turning RIght (less than two millimeters) there are two points: Before or after the correct point of stop? Regards Wolf Ulrich It stops beyond the correct point. It should stop earlier. I have tried with Position_R parameter but: either it does not change anything or, when the pa...

Re: Wrong positioning when turning right

Hello Andrea, Reflector disc: the black parts are not really black! Take a felt-tip pen to make this parts really black! I used glittering white photopaper and after print the felt-tip pen to correct the black parts to deep black! Addendum: I tested also the following method with very good results ...

Re: Wrong positioning when turning right

Your Parameter: - V_Mess and V_Count are near the upper limits! - Pos_detection L and R are at the lower limits! - motor current L and R more than 10% R to L ( mechanic/motor ) - FastSpeed L and R are lower then the Lowspeed! You are referring to the old parameters setting, partially changed in the...

Re: Wrong positioning when turning right

Why is your sensor before the white mark, and not on it?
Is your sensor really connected correctly?
I do not know. However, when turning to the left, it works and the rails are well aligned.

I'll be grateful for any contribution to solve the problem

Re: Wrong positioning when turning right

starting point before turning one position to the left
starting point before turning one position to the left
one position to the left reached
one position to the left reached
back one position to the right: clearly WRONG position
back one position to the right: clearly WRONG position
Please let me know how to correct OR else how to have the platform to turn ALWAYS to the left (the only turn that works perfectly)

thanks

Re: slack between metal shaft and plastic gear

Hello, the "slack" has no influence at all - don't care about this. There ist no slack from the sensor input and the position. the slack from motor to sensor is not interesting. Sven My explanation was not very clear: the "slack" was not between sensor input and motor, but insid...

Re: Wrong positioning when turning right

Possible, if you set all "RIGHT" Commands (DIR, STEP, TURN) to the same address as the LEFT commands. So no matter if the DSD gets the command to turn Right or Left it will always turn left. But TC might be confused that turning one step right will take such a long time (47 Steps left), s...

slack between metal shaft and plastic gear

In my mechanism that moves the platform, there is too much "slack" (hope is the right English word) between the metal shaft and the small black plastic gear. For "metal shaft" I mean the vertical shaft that brings the motion vertically down, to the round metal gear that moves the...

Re: Wrong positioning when turning right

Thank you Sven for your reply. I have increased the "right low speed" with some good results, but not always acceptable. I attach two screenshots taken at full speed: the first when turning left, the second when turning right. However, in these tests there were no random stops. Unfortunate...
