Subject: BackLash in Slave mode
Hello,
I am new to the group, I'm French so excuse my English.

I have a 3 axis CNC donations the X-axis is doubled.
Motorize Step / Dir in open loop.

My problem is in mode Master / Slave, Slave not doing its backlash.

Is this a known problem?

Salut,

Désolé mais je n'ai pas compris exactement quel était ton problème.

Si je décode, tu as un système trois axes avec l'axe x dédoublé comme pour un router ou similaire? La motorisation est assurée par un système stepper et tu veux assurer le contrôle du jeu?

Merci de corriger et compléter en fonction.

Jerome

Hi Fredy,
 
Yes that is a bug.  This new KFLOP Firmware should fix it.
 
 
You must be running V4.29.  Copy the file to the DSP_KFLOP directory (without changing the name).  Flash "New Version".
 
The firmware should report the Version as 4.30x
 
Please let us know if it resolves the issue.
 
Regards
TK

Thank you,

It works, but we must put the "BacklashRate" in negative.

Oui en faite ma fraiseuse fait en gros X2.6m x Y1.6m.
L'axe X est doublé et motoriser par deux moteurs Pas a Pas.
Ces 2 axes sont déjà très vieux et n'ont pas le même jeux, cela reste quant même dans les limites de quelque centième.
Je tournais encore sur la version 4.28.

Grâce a l'intervention TKSoft j'ai put régler mon problème.
J'ai d'autre petit problème mais je reviendrais plus tard la dessus.

Merci encore .
