What is M208?
Another "victim" of the configuration tool - it has shielded you from learning the commands.
M208 is used to set the axes minimum and maximum positions.
For example on one of my printers I have this: M208 X-150:150 Y-100:100 Z0:300.
What is means is the range on...
- the X axis is from -150 to +150
- the Y axis is from -100 to +100
- the Z axis is from 0 to 300

@TomasL It's just FINE that you are confused and having problems.
We're here to help you and we will get you going eventually. We've all been confused with this stuff also.
Stay POSITIVE and you';ll get the best results from this group.
You can look up all the G and M codes here.
Here's M208
So, let's start with this:
- Move the carriage away from the X, Y and Z limit switches and post the result of M119
- Press the X limit switch and post the result of M119. Release the X limit switch.
- Press the Y limit switch and post the result of M119. Release the Y limit switch.
- Press the Z limit switch and post the result of M119. Release the Z limit switch.
This will show that each limit switch is hooked up correctly and working correctly.
Then we can move on to homing.

@TomasL said in Multiple problems:
I guess that is the offsets from the limitswitches.
Well, when the X-switch is activated, the head is around 18mm out of the bed, same with the Y-switch, the Z I had set just to avoid it craching into the glass. for the moment.
Maybe I got it the wrong way aroundOK that value for Z then makes sense as it is only for testing.
Can the end stop switches be adjusted can reach the edges of the printable area?

the motor test macro
What motor test macro? Was it on the SD card? If it is the same as my SD card that macro is for factory use.
Frederick

Ok, Ill have to do that tomorrow, since the printer is in my lab and I am at home , by the way, this is my lab
Yes, the macros show upp in the WEB-UI -
@fcwilt said in Multiple problems:

OK, then in M208, you want X-18 instead of X18
Then, in homex.g the command on line #9 G1 H1 X-228 F360 says to move in the negative direction until the endstop switch is hit, and THEN set the current X location at minus-18mm which is what I think you want.So a similar thing for Y and Z
-
I see the problem.
You don't own enough test equipment.
Are those scopes Tektronix? What models?
Frederick
-
Any macros that came on the SD card should not be run. They are for factory testing. These macros are no longer included, but boards that were purchased before the change may still have them.

Nice lab!

If I am allowed to do som "commercials",
I run two sites, (well three sites really).
They might be usefull, since all information is free.
The first site is ebaman.com, where I collect users/service manuals and other documents, for full free download, the only catch is that you have to register to download.
I have the largest collection of Heathkit manuals available, plus some 13k of other manuals.My next site is ba-restore.com, dedicated for restoring boat-anchors (well for you that dont know what it is, old electronic and mechanical equipment).
The third site, is microdiscray.com basically this site describe how crazy I am, since my intention is to build a MIPS32 CPU/Computer in discrete components based on ECL-technology.
When I'll get some $10k or so available, I would probably build it.
Anyway, I am happy for all help I could get
Btw, here is a picture of Frankenstein
-
Well, the Lab
Right, what do I have in there, well:
One TEK 7854 computing mainframe with calculator.
One TEK 7603 with 7D20 Digitizer
One TEK 7613 Storage with Curve tracer
A number of various TEK7000 series Plug-Inns
One Nicolet 4094 Storage scope with dual 5 1/4 Floppy-Drive.
One TEK DPO7000
One HP 2GHz spectrum analyzer
One Agilent 6,5 digit DVM
One Fluke 8854a 5,5 Digit DVM
One fluke 8000 DVM
Various fluke handhelds
One handheld Agilent LCR-meter
One TEK 1241 96 channel Logic analyzer
One TEK 308 8-bit +16- bit Logic analyzer
One HP Counter
One TM500 with a number of various modules
3 weller WX soldering stations, 40, 80 and 200W
1 Weller De-solderiong station
One Hot air soldering station
2 Leica Stereo microscopes with lightassembly
One 3-d Printer
And to finilize the whole stuff, one complete SMD Pick and Place assembly line -
Fredrick, I know, I need to get some more stuff.
On the purchace list is a Wow&Flutter meter amongst others. -
I worked at Cray Research Inc for 16 years, so I know "Seymour" Cray's work well.
If you don't like integrated circuits like he used in the Cray-1, try looking at his previous machine, the CDC 6600. It's all transistors!
-
alankilian, will certainly do, however, the thing is, I can DO IT.

@TomasL said in Multiple problems:
One TEK DPO7000
Thought some things looked familiar.
My company, many many years ago, sold an interface between the HP 9830 Desktop Calculator and the DPO.
We also had an interface from the 9830 to the Tek computer terminals that used their CRT storage technology.
Ah... the good old days when the Z80 microprocessor was "hot stuff".

Here's my lab before I had to shut it down due to COVID-19.
I'll be back in a new lab in December 2021
-
The DPO7000 is basically an PC with some addon-cards, it runs WindowsXP , but it is an 1GHz scope with 4 channels, so it is pretty awsome.

That must be newer version than the one we worked on - ours had no processing at all - everything was done via an external device.
And if memory serves me it used core memory.

Fredrick.
I am a HP-fan, I use an HP41 as my standard physical calculator.
I also have an HP97, that needs some restoration as well as an HP71B, together with HP-IL for the 71 and the 41 and an IL-printer.
When I get my Frankenstein -printer working, I have to print some spare parts for my Teletype model 33 ASR as well as for my Nakamichi 582 tape-deck, amongst others.
The Idea I have is to print hammer-rubbers in rubber-filiaments and to cast printer-heads for the Teletype (with lost-wax), since these currently is made of un-obtanium. -
Anyway, Ill be back tomorrow, when I have done the tests on the end-stops.
