Incessant "Wait" Commands

JakeM

<font face="Arial, Verdana">I have an Arduino/RAMPS loaded with Repetier Firmware that I am trying to get set up with Repetier Host. However, when I connect the printer to Repetier Host in the log it just says "wait" over and over. I can send commands to the printer; however, the motors will not move and I recieve the message "Warning: Seems like we missed a ok, got a wait - continue sending."</font><font face="Arial, Verdana"> I have checked the baud rate in the firmware and host and they match. I also have the correct COM port selected. I was able to upload sketches to the Arduino so I assume that I have the right driver installed. Any idea what is happening? </font>

Repetier

Firmware sends back a "wait" if it did not get any command in the last second. As you receive this the baudrate/port/driver is ok.

What happens if you send M115? Should return some infos in log. Also if you press reset on ramps you should get a bunch of output in log.

Can you enable logging and show the log content after a login. That log file (in work directory) contains everything and maybe a hint. You need to restart to enable it and close host to read complete log. Next start of host deletes old log file.

I got the same problem. The output of M115 is: Please advice!

Repetier

wait is no problem. If you are not printing it is normal to see them from time to time. Log looks absolutely perfect.

rivael

The wait message corrupt the Repetier-server <--> Repetier 0.91 communication.

I can't use the usb cable to control my printer. I need to use SD card and display control and buttons!

OK message are not interpreted and wait(4) message are accumulated.

how do I disable this message?

(Or maybe I have another problem with the Arduino here)?

Please advice!

MartinH

De select ACK at bottom of repetier host, this will stop the 'wait' messages

rivael

I couldn't find the ACK. I am running repetier-host version V2.0.5. Where is it?

What should I do in Repetier-Server?

MartinH

Repetier

Server has also the ACK switch in commands, the only place where you can see the wait in the server.

rivael

Oh. You ask me to disable the ACK message from the Arduino. Well, I did and nothing changed.

Well, I do have a communication problem with the Arduino. I can use the printer with SD card only.

In the following log, you can see I attempt to send G28 message to the printer with no luck:

That´s the interesting Lines... it Shows that you have Problems on Power Supply.

Reason may be that Arduinos Onboard Regulator is overloaded or Power Supply is a Bad one.

Thats where to seach

Repetier

wait is not your problem. You have lots of communication errors and the brown out also does not help here. Might even be a reason communication is so bad. In fact the waits here help you resolve blocks much faster. Otherwise you would have gotten a "timeout" delay on each of these errors. SO be happy to have them.

rivael

Thank you for your replies!

I have many things to investigate now. :-)

rivael

I have changed the power supply, and now I don't have the brown out message.

But beside that - everything are the same:

Repetier

That is ok. Not perfect as you have communication errors, but most printers have more or less frequent com errors. The message just says it detected one and fixed it. Of course you can try different cables and baut rates to see if they get less, but as long as they are not too frequent you can good live with them.
