Topic: A question about my DaVinci 1.0A with Repetier

Things are going well overall with Repetier on my printer.

I have Simplify 3D working very well.  Repetier Host with Slic3r is working ok but for some reason the prints seem to lift a bit.  I am sure it is some settings I need to tweak.

I have noticed an issue that is not a big deal but requires me to reboot my computer (windows 10) occasionally.  The printer usually shows up on COM11 as a USB device.  It connects and works well.  However, if I turn the printer off and on, it changes in device manager to COM10 and then is reported as an Arduino Device.  Rebooting my computer fixes this but I wonder if there is some setting I need to tweak somewhere to stop this behavior (perhaps in Windows).

Any thoughts?

Thanks

Does anyone know of a way to stop this behavior or why it is occurring?

Re: A question about my DaVinci 1.0A with Repetier

mpoffo I'm new to 3D printing but not new to CAD/CAM in fact that is my line of work as a design Engineer. However I just got my DaVInci  1.0a three days ago and I am thinking of going with the Repetier .92. This might seem like a dumb question but after watching several yuotubes on Repetier, I cannot determine if Slic3r is included in the package. Also do I need to flash my Printer before I can use Repetier?
Thanks!

Slic3r and the Cura slicing engines are included within the Repetier Host program you need to download.  I believe they both have standalone versions you can use as well for slicing.  They are included in the Repetier Host program as sort of an "all in one" solution.

The repetier firmware needs to be flashed to the printer if you wish to use the Repetier host program.  It also opens up the printer to do many other things and frees you from the confines of XYZware.

This is a resource thread I created that may be of some help:

Yes Thanks! I did read your thread yesterday and makes perfect sense.

Re: A question about my DaVinci 1.0A with Repetier

lifting of the edges is common when printing with abs.

here are things that can negatively affect your print and cause more lifting:

The bed not being level.
the nozzle being to far away from the bed on the first lvl.
the fist level being supper thin
the bed not being hot enough
long thin prints
not using glue like uhu (you can use others as well or hair spray. I find hair spray doesn't work as well as the glue for abs but works good for pla. but the uhu glue works well for pla as well) often I may skip the glue if I want a really smooth print as the glue does reduce that hair spray is better for that then glue but nothing is still smoother)  if you don't use glue getting the right distance between the nozzle and the bed is very very important.

Things that can be helpful in keeping a print from lifting:

a brim ( this essentially increases the first lay surface which can help resist the curling an even if you do get some usialy its just the brim that lifts.

a raft (this can help if your bed suffers from not being flat)

Putting scrap throw away parts near the corners and making sure the brim from the corner touches the scrap part (example putting a 5 mm circle near the corner when you design the part and then setting it 3 mm away and having a 3 mm brim)

I'm sure there are more but those are the basic ones.

Re: A question about my DaVinci 1.0A with Repetier

I got my lifting issue taken care of.  I use kapton sheets and they work well.  I had to adjust my bed a hair to get a more "squashed" first layer like I had before.  I do use brims/rafts in Simplify 3D frequently.

The more "annoying" issue is the issue I mentioned about the printer's com port in windows.  On boot-up it is com11 and will stay that way unless I reset the printer by doing an emergency stop or turning it on/off then is shows as com10 and is an Arduino device.  I cannot connect to it on com 10 so I have to reboot.

I was hoping someone may have some advice on that issue.

Re: A question about my DaVinci 1.0A with Repetier

I would think just unplugging the USB cable and then plugging it back in would work.

Mine did a similar thing in Windows 7 so if I needed to turn it off and on I would unplug the USB first. Then power cycle and plug the USB back in once the printer had fully initialized. I don't really think the USB interface used by the Da Vinci is that plug and play compatible.

Mine does not do that unfortantely.  Requires a reboot.  When I go into device manager and look at the properties of COM10 and go the advanced settings, it lets you look at the other com ports.  it says 11 is in use but still cannot maintain the com port unless I reboot.

Maybe this has something do with the drivers installed, windows 10 or some combo of them.  I am hoping someone with more technical expertise might be able to help.

Try my method and see if it makes a difference. Before you turn off the printer just unplug the USB. Then turn it off. Once it is turned back on, plug in the USB. The issue is which device Windows 10 sees at first. If you leave the printer plugged in and power cycle windows 10 scans the USB ports so fast that it actually sees the boot loader come up and so identifies the port as an Arduino device.

By unplugging the USB power cycling and plugging back in you are allowing the firmware to load and for the board to come up as a USB to serial device as it should and Windows 10 should see it as such.

I think the issue is that Windows 10 can scan USB ports much faster and Identify them faster than previous versions of Windows. I don't think there is really a fix. So in this case Windows 10 is able to scan and see the boot loader before the firmware loads and your printer is booted fully.

This is a good suggestion but unfortunately it did not work.  I try different combo's but the printer port the printer usually uses is busy.  Some how it is not being released as available.  Quite frankly I am not sure if this is how this is suppose to work in Windows 10.  I wonder is there is some other way to "flush" the ports instead of rebooting.

It is connected directly though I have this USB connector:

I am going to be installing a wifi SD card so maybe this is a moot issue but I would like to figure it out if I can.  This was not an issue before the flash.  So something with Arduino maybe and how it is detected?

Re: A question about my DaVinci 1.0A with Repetier

So I have been doing some snooping and seems there may be an issue with Arduino and windows with respect to higher comport numbers. While the printer is connected open it's port properties. Then advanced properties and change its port number to the lowest number you can get with exception to 1. Then see if you have the same issue.

I would highly recommend the wifi SD card route, it's so much less hassle than printing over USB.
I always found printing over USB very hit or miss but printing from SD is much more reliable.

Re: A question about my DaVinci 1.0A with Repetier

I have Windows10 and the same issue (not sure about that change to Arduino device when on and off the printer but do needing to restart the computer if the printer turns off and then on to reconnect to Repetier-Host). I did this same question here some days ago.

Strangely, yesterday, when dealing-trying with Simplify3d and Repetier-Host, after the off-on cycles of the printer (because of bed leveling and stopping failed printings -bad temperatures from S3d that I still have to investigate-), Repetier-host connected with the printer without restarting the computer. I don't know what I did to get this positive behaviour despite using S3d.

I'm sorry if this comment has no sense. Have you tried to change the com port in Printer Properties of Repetier-host? I find that after the turning off and on of the printer, this com port changes (not sure if always or sometimes), and it could be necessary to readjust that setting.

In my case, when trying to reconnect from Repetier-host the error message sometime says "the port doesn't exist", then I fix the com port in Printer Properties (I see there that the previous com port is wrong) but another time it appears an error message when trying to reconnect: "denied access". So that for me this change of com port isn't a solution but... could it be for you?

Mark, what about painters tape?

Here in Spain the blue painters tape is not usual (rare in shops actually), the painters tape we use is off-white, a bit coarse surfaced that, maybe, isn't good to stick the parts on the bed (I haven't tried yet). But I get from some users, here and in youtube, that the blue one is pretty good for 3d printers, avoiding glass breaking and sticking parts well to the bed, so I'm a bit curious to know why don't you mentioned it in your above wonderful comment.

Re: A question about my DaVinci 1.0A with Repetier

the tape just keeps you from damaging the bed nothing to do with sticking.


if your printing on a glass heated bed don't use painters tape (well you can but I don't). Even with painters tape you still need glue or hair spray.

I do use it on my printer that does not have a heated bed and I find I still need to use glue or hair spray to get prints to stick well.

Re: A question about my DaVinci 1.0A with Repetier

Painters tape is used for PLA on a cold bed for sticking. On a hot bed it is used just for protection as Mark said. it's adhesive does not hold up well under heat and the tape itself will pull up with the edges of the print. If you have a glass heated bed just use glue or hairspray for pla  or both plus abs goop for abs.

Do you think that painters tape could be a preventive measure against the bed glass breaking (which is a common issue, as far as I know, in Da Vinci 1.0/1.0A)?

The breaking and chipping is caused by thermal shock and cheap glass.

The painters tape will do little for that.

Re: A question about my DaVinci 1.0A with Repetier

Thanks for the replies.  My issue is not really with things warping.  That was an adjustment issue all taken care of now.  smile  I use Kapton sheets and they work well and last a long time.  I personally don't like painters tape but I heard it is better for PLA.

I will try Carl's latest suggestion about the com port issue(lowering).  To be clear to others that posted I have no issue connecting in S3D or Repetier.  It is an issue with the com ports, windows 10, Arduino and the printer.  I'll let you know what I find out.

I got my wifi SD card today unfortunately the nice folks at Amazon sent me the wrong adapter so I have a new one in coming next week now.  That will be my preferred way I thing once I can get things hooked up and working.  I do wonder how the stock firmware could upload relatively quickly to the sd card in the printer will it takes considerably longer with repetier firmware.  I am sure there is an explanation.

Re: A question about my DaVinci 1.0A with Repetier

Repetier use different way to upload file than XYZ
XYZ send the file as it is
Repetier send GCODE line by line by interpreting them once on host and once on printer to check integrity so it take far longer than just push the file.
Wifi SD card is far the fastest way to upload IMHO
