Hi Rich

I can't open the pictures, can you post in the Photo section some jpg type files ?

Skidoo 670HO

Well, don't know what happened to the rest of my previous post, but has anyone here ever made any Billet Snowmobile Head Inserts?
 
I was wondering what kind of machine, it would take to make a dual angle plug insert similar to this one below?

I want the upper part to look like the one above, and the bottom to look like this one on the bottom.

Hello:

Don't have any cnc yet. Hobby guy, still all manual yet.

Never mind my previous post.  Looking back I you have already answered the question.

Replacing all the transistors seems a bit extreme.  You could start by using a DMM in diode check mode and compare the readings between similar transistors.  A failed transistor should stand out.  

Perhaps Henk will elaborate on the implications of your measurements.

Your observation that the z axis doesn't move at minimum speed begs another question..  Have you tried plugging your Z axis motor cable into the X axis stepper connector and tried running it as the X axis?  Your  Z axis may be mechanically frozen.

Henk put up some really good data, but im not sure how to interpret my measurements ...

some are zero when they should be 5, and when i turn it on, they are good, except one or 2 that are more than they should ...

i looked for desoldered components, but i didnt found anything. 

any ideas on what i should do next?
Thanks

Search this groups conversations for "trouble with stepper motor interface".  The thread you find may help you.

Re: compact 5: advance motor "humming"

It is on the Z-axis only, the X-axis work fine (as the spindle motor:) ).
i know for fact that the motor itself work fine (when i plug it into the other plug it work perfectly)

i puled the 113.001 board (the stepper board) but i don't know how to test a transistor ...

the motor "humm" wen i try to move it in low speed at high speed, it just make more noise, seem to vibrate more, but does not move any better ...

Re: compact 5: advance motor "humming"

I had a similar problem on an F1 years ago.  The problem turned out to be a defective transistor on the stepmotor board specific to the bad axis.  The function of the transistor is to initiate motor stepping by switching to the high voltage (40V) at the start of each step.  

Try moving the axis at minimum speed.  If it moves you probably have the same problem.  I can't find any notes on how I determined which part it was so I can't be of any more help.

Walt

Hi Sebastien
Your problem is only in Z motor ? You could exchange the motor cable X with Z (rear the lathe) if the problem after exchange is more in Z motor then your motor is dead. If after change the problem is in X, I think that the problem is in the electronic card.

je devrais être plus précis dans ma description:
le moteur pas à pas dans la direction Z est fredonner.
je suis arrivé à tirer le conseil vérifié 113,001 aujourd'hui la moitié de la capacité et aucun problème jusqu'à présent.
est le pont de diodes sur la carte 116?
une fois que je trouve, comment je le tester?

merci pour votre aide

Hi, is the X (cross slide) motor working OK ?
If X is OK then the problem will be most likely on the stepper control board, not the Bridge rectifier I said earlier when I thought both axis were not working. The Bridge rect is about 1.5" square shape and has 4 connections on it, 2 for the AC in from the transformer and 2 outputs which are DC. Look inside the back at the top right of the control cabinet.

i should be more precise in my description:
the Z-direction stepper motor is humming.
i arrived to pull the board 113.001 today checked half of the capacitor and no problem so far.
is the diode bridge on the board 116?
once i find it, how to i test it?

thanks for your help

Merci, Le travail de la tourelle maintenant :)

im nouveau à la machine CNC et mes compétences en réparation électroniques sont plus de base ...
 je ne pouvais pas localiser le pont, nous, sur le bord, le moteur de brancher, le conseil sur le dessus de celui-ci (avec prise de vidéo) ou le bord avec le commutateur de relais bir? ou est-ce un sur l'autre?
Aussi, j'ai trouvé le schéma dans la section du fichier, mais je ne suis pas sûr que l'on à suivre ... ni par où commencer ...

merci pour votre aide

Thanks, The turret work now :)

im new to CNC machine and my electronic repair skills are more than basic ...
 i couldn't locate the bridge, us it on the board, the motor plug in, the board on top of it (with video plug) or the bord with the bir relay switch? or is it on another one ?
Also, i found the schematic in the file section, but im not sure which one to follow ... nor where to start ...

thanks for your help

Hi

To test the tool turret when in manual mode hold down the FWD button and press a number between 1 and 5, (release the buttons when movement starts) the tool turret will advance by the number of tooling points of the number pressed.
It will stop as it passes a tool station and reverse back to the stop, hold momentarily and then advance to the next tool station and repeat the moves, this will continue at each tool station it passes.
Don't forget you are moving number of" tool stations" not the tool designated number.
There are schematic drawings in the files section, sounds like you have lost the 30/50v initial pulse to start the stepper moving. Check out the Bridge Rectifier fitted at the top right of the board above the PSU and contactor. If that's OK check other voltage outputs as shown at the test points on the circuit boards in the schematics.

Hi folks 
Now all is ok I send photos about my configuration  the Thread wizard done from a friend 

Re: Threading Cycle with Mach3

If I am understanding you correctly - when you change the spindle rpm while cutting a thread - you don't see the threading stay in sync?  I think mach assumes the spindle speed is constant..  (it can't adjust the cutting much if the spindle changes speed)

Hi Benny
Tks for your answer, so in my test I've 300 rpm in emco's display and a big number in mach3 display, if I change rpm in emco I've not change in thread speed, I think that normally if the rpm change also thread speed change.
Regards
Natale
