DUEX 5 V0.8 TO DUEX 5 V0.11

paolozampini1973

@engikeneer In practice my printer is composed in this way or four extruders with 4 nema 17 Then I have the Z axis with two motors then I have the x axis controlled by the external driver dm860h and also the external Y axis controlled by the Driver dm860h everything works on 15 mm linear guides with SF1204 screws and the loss of step I had only and only when I was going to make the seams Tighter than 10 mm if I don't do the seams I have no problem I can easily turn 120 even 160 mm without No loss of step but if I go to do the seams seams I lose the step even 50 mm this with two ex 5 well V 0.8 this is the only problem I had and now I find myself six problems to solve what I say but if a person spends money to have more problems than before honestly he has no logic I hope to be understood and understood why I would not have spent more money to have more problems usually more money is spent to have less problems in this case I have spent more money to have more problems I hope I was clear

@paolozampini1973 said in DUEX 5 V0.8 TO DUEX 5 V0.11:

@engikeneer I have 8 motors to manage so I have to use it as a duex 5 and not in a modulated duex2

If you have the duex5 in duex2 mode surely you can connect your external drivers to 2 of the 3 axes available on the BoB. You then have 7 other (5 on duet, 2 on duex) for your other axes. If there is a good reason this won't work I am happy to be corrected.

@tekkydave start to think that it is I who do not explain myself well or someone cannot understand my problem but strange because I have explained it as many times as possible every time I am wrong to explain my problem then there is another speech each one gives I am pleased with advice but you cannot give advice and then not follow the advice because in this way you do not get to really anything so if someone can be so kind and courteous You should follow the problem is that if someone gives me advice and then it disappears is no longer heard is useless Anyway thanks

paolozampini1973

@tekkydave however in all this I am really curious if someone really wants to help me because as I have already said at least 10 times with the v 0.8 I did not have any kind of problem a problem that I had a loss of step on some print seams and now I find myself with 6 problems so INSTEAD OF IMPROVING AFTER I made a V0.11 upgrade the facts say that I did a downgrade I don't know if I practically explained myself by switching to V0.11 I should have made a qualitative leap and solved all the problems instead I find myself with 6 more problems I do not know if I have explained myself but no one will follow my problem nor even the engineer because I do not think that all these conversations have not read it AND in any case the V0.11 has problems

paolozampini1973

@dc42 Good morning I have been trying to talk to you for several days obviously you are very busy I can understand it but I want to talk to you about the problems that exist DUEX 5 V0.11 at least tell me if you are interested in talking about the problems that exist on the V 0.11 at least answer me I ask you please please THANK YOU
believe me I have been waiting to talk to you for a long time several days I let you know if you are interested because I want to talk to you to clarify some problems on this v0 11 since in v08 I did not have all these problems Thanks again

@paolozampini1973 If we ignore the fact that you are unhappy with your purchase will my suggested configuration work?
I have 41yrs experience as an engineer and programmer and find the best engineers are the pragmatic ones.
As an inexperienced database developer I used to get very upset and obsessed when a proposed solution wasn't perfect. One day a DBA I looked up to took me on one side and just said "Don't be a dick, Dave".
If anyone else following this thread can say whether my proposed solution makes sense it might help the OP.

@tekkydave my printer configuration:
Z is configured with two INDEPENDENT motors FOR SELF-LEVELING one on Driver 1 = Z one on the driver 9 = Z then X = DRIVER 7 EXSTERNAL DM860H Y = DRIVER 8 EXSTERNAL DM860H then I have 4 driver instructors 3 TMC2660 + driver 4 TMC2660 + driver 5 TMC2660 + driver 6 TMC2660
PROBLEMS WITH DUEX5 V0.11 IN DUEX5 OFF DRIVE MODE 7 AXIS X + DRIVER 8 AXIS Y WHY I NEED TO USE IT

HOW DO POWER SUPPLY X + Y GO WITHOUT ANY DATA COMMAND
HIGH TEMPERATURE M906 I TRIED TO PUT ALL AXES AT 0 MHA THE PROBLEM PERSISTS CONTINUOUSLY THE TEMPERATURE DRIVE TMC2660 AND 24 ° DEGREES
I ALWAYS HAVE THE SAME STEP LOSS PROBLEM AS DUEX 5 V0.8
THERMOCOUPLES REPORT 18 DEGREES LESS

I hope that now I have been clearer How I repeat all the problems I have with the V 011 I did not have before I only had the loss of the step on one type of seam and that's it now These are the main problems I find myself

paolozampini1973

@tekkydave I have to be honest I did not understand your solution which is I repeat and repeat and repeat and repeat I have created enormous problems disassembling DUEX 5 V 0.11 before I did not have these problems because before I did not have these problems question

paolozampini1973

@tekkydave I am willing to do all the tests you say but before doing any tests that I did not understand what you explained to me because I do not speak English very well please answer please please and please I did not have all these problems i had only a small problem the printer worked fine and i didn't have all these problems please help me understand why now with the V 011 or all these problems instead of upgrading i did a download the facts say this would you be so kind to explain to me thank you

paolozampini1973

@tekkydave maybe I can't explain myself I mean I'll give you an example that has nothing to do with it You have a car with an engine that at 200,000 km but works well gives you just a few small problems You mount a new engine and the car gives you many problems with a new engine then either it is the engine that is not good or you have the wrong connections But yes the connections are the same and identical because the engine is not working well This is what I am trying to understand I hope that I have explained myself Thanks for your attention

@paolozampini1973 Great! Some information at last! So currently:
Duet 2 drivers 1 (Z1), 3 (E1) and 4 (E2) are in use, 0 and 2 not used.
DueX5 drivers 5 (E3), 6 (E4), 7 (X, external), 8 (Y, external) and 9 (Z2) are in use.

Seems like the obvious solution is to move the Z2 axis to the Duet mainboard, driver 0 or 2. Then run the DueX in DueX2 mode, as has been already suggested many times.

Also, post your config.g and M122, as I've asked before.

I don't understand what you mean by this:

HOW DO POWER SUPPLY X + Y GO WITHOUT ANY DATA COMMAND

If you mean how will X and Y get step commands in DueX2 mode, don't worry, it will.

droftarts

@paolozampini1973 Of course, running the external drivers on the DueX still doesn't resolve the original problem of your external drivers needing 5V signalling.

Ian

paolozampini1973

@droftarts config (17).g i mean that in DUEX 5 mode WITH DIRVER7 TMC2660 + DRIVE 8 TMC2660 OFF AXIS go on the move as soon as I turn on the electronics they instantly move very slow but they move as soon as I turn on the electronics I hope I was clear they remain still only when it is in DUEX2 mode which is a mode that I cannot use for my configuration and I repeat I did not have all these problems with the V 08 I did not have all these problems Only problem was a small loss of Step now I have all these problems as I have already listed before why

droftarts

@paolozampini1973 In DueX5 mode, the Duet 2 will be trying to communicate with the drivers, and the external drivers are picking up the signal. That is why you need to disable them by using DueX2 mode. As I said before, move the stepper motor on DueX driver 9 to the Duet 2 board. Why can't you do this?

For the other issues, please please please please post your config.g and M122.

@droftarts I have mounted the 74hc 14 but the problem has worsened on the stability and however it goes Iasi they go in motion without any command I repeat again I did not have this problem before mounting the V 011 now I have also mounted the 74hc 14 okay I have it done But it is even worse because it loses much more so after making all these changes I have made the problem worse I have not improved the problem what I say guys I agree with you but if I give him 5 times he still loses me the more I pass but I immediately lose any movement so the facts say this is not goodDM860H V3.3 act英文 (1).pdf
there is what I try to say is that by putting even more electronics even more modern even better but I have more problems because thanks

paolozampini1973

@droftarts Yes I can also teach them abitare 3 nema 17 I throw them it is not a problem but it is not normal that before with the V 08 I did not have this problem you tell me that I owe them if living is not a problem I just detach them I disassemble them from the printer but so I was still another problem So it means that then three other motors I as command and then because before I did not have all these problems and now I have this problem with the v08 I did not have these problems understand that I want to tell you please can you explain it to me. Thanks

paolozampini1973

@droftarts Please excuse me but what I want to understand if before I did not have these problems because now I have these problems with this new version I should not have any kind of problem and instead I have 4 new serious problems of the other Please explain me
That is, for me all this is a contradiction because I should not have had these problems with the V 08 I did not have these problems I had only a small loss of pace please please please try to explain to me why you tell me to go IN MODE DUEX2 Okay but why do I have to disconnect three engines that then I don't know how to drive them anymore and therefore I still have another problem I want to understand Excuse me for my very bad English

paolozampini1973

@droftarts I want to ask a question I do not know if I have explained myself you have understood that for me the problem has worsened a lot to install the V 0.11 for me it was much worse I have a lot of problems so many problems that I did not have before please answer me if I have been clear Please please

tekkydave

@paolozampini1973 Yes you are correct. But now you have two choices:

Accept that your new engine is crap and go back to the old one.
Take some advice on how to work round the issues you have and fix them to get your car working again.

You seem very reluctant to take option 2. If you read back over the advice in this thread all the answers are there. If you supply us with the information we have asked for - the output of the M122 command and your config.g we can help even more.
