Crossfire Error Code 740

[Filomeno Robles]

Whenyou set up your tool in CAM, you must set the Pierce height and Cut height to zero. If those values are not zero, the post processor will include the IHS(initial height sensing loop) in the code.

@ds690 is exactly correct. If you do not have a Z-axis installed on the machine yet, then Z-axis commands that are included in the G-code will result in an error message. You will need to disable the Z-axis commands for now until the Z-axis kit is installed on the machine. If you are using Fusion 360 to create your G-codes, you can find more information specific to this here:

Generally, this error is caused when you try to run G code for a machine with a powered Z axis on a machine with no Z axis. It can also be caused by a disconnected or broken wire on the IHS system, on a machine with a powered Z axis.

OK, that is a different issue than the IHS Fail error. The IHS system is programmed to probe downward, up to 5 inches, or until the switch opens. If the Z axis thinks that it has moved at least 5 inches and the switch has not been opened, there is likely a problem with lost motion on the Z axis.

As Phillip suggested, you should check the coupler between the Z motor and the lead screw to make sure it is tight. There have been many reports of new machines with a loose coupler that allows the motor to spin without moving the lead screw.

Turns out the barrel clamp that connects the wrom gear of the x axis to the stepper motor was lose on the motor side amd thats what was causing my fault. Thanks everyone for taking time to lend ideas and possible causes

Now it's October and it start to get cold. I was out and driving my Crossfire and thinking, it was long time ago I had to do some repair on it. I stopped the car and visit a store. When I came back and turn the engine key the engine crank but it didn't start. What ! First I thought it had something to do with the car alarm. Then I remember that I have read that the crankshaft position sensor is a common device to fail and then behave like this. Luckily enough I already one year ago ordered a new crankshaft sensor and stored it in my car if this problem will occur.

After I had turn off the ignition the "Check Engine" lamp has turned on. I let the engine cool down and after my third attempt to start the engine it started. I was only 10 km away from home and it's much easier to do some research at home about the details. When the "Check Engine" lamp is light up there should be some error code stored to read out.

The error code P0335 say that the crankshaft sensor or its cable is bad. It could of course be something else but this is a very common problem. I have collected some information about the OBD II reader here that I have used at earlier repairs.

Looking in my car and found the crankshaft sensor I bought one year ago. It's not a Bosch but a Topran, I hope it will work. But how to replace it ? I have already when I worked with the car earlier noticed that it was located on the backend of the engine on the top side.

Mercedes use a lot of these inverted Torx head screws. In this case the screw that hold the sensor is of the size E8. When looking after what tools I have I found one that fit, but this is not not a 1/4" shaft, it's the bigger 3/8" size. That was bad because the space is very limited around the sensor.

Kind regards, I have problems with my stryker crossfire 2 electrosurgery equipment, which throws me an error code 39, and I require guidance and information on this error and how to solve it. in advance receive a strong hug. Atte: Ing. Alberto Pimentel.

I saw many videos in YouTube showing working CrossFire in GTA V and Project Cars 2, so this makes me think that something is wrong somewhere, I do not know yet where. Is it an operating system's bug, or is it a driver's bug, or is it game developers changing their game engine suddenly (can not imagine it really).

I saw old games in full HD resolution showing good FPS scaling with CrossFireX. But now all this is history.

Thank you for the information. I have found a solution -- to sell a computer and go for a walk. Seriously.

You might get better results by using older drivers, not newer ones. Most of the games that will make good use of CF are going to be fairly old at this point, so wouldn't benefit from newer drivers anyway.

The built-in AMD CrossFire profile for Project CARS 2 does the same thing as the latest stable driver with the default mode for CrossFire. 55 FPS at the sunny Brands Hatch start straight with all high settings and low GPU usage on the second card.

The CPU is not always loaded in PCARS2. The most loaded core is the first core and its load varies from about 40% to 90% according to the FPS Monitor. The maximum load of the most loaded core can be seen only in about 25% of the time, so it seems to me that the CPU is not a bottleneck here.

What resolution settings are you running with?

I am downloading Project Cars 2 on Steam now.

If you are running it on Steam, turn off Steam Overlay.

Turn on the CrossFire logo oto make sure Crossfire is engaging.

I already have GTAV .

I have a pair of Gigabyte RX590s.

I could fit those on the same machine, but performance on a pair of R9 Fury X 4GB HBM should be similar to a pair of RX 580 8GB cards.

Lets see how the R9 Fury X do first though.

OK?

Scaling of 2.0 is high so likely a bit of measurement error for those figures.

However Crossfire DX11 is definitely working and showing good scaling on GTAV at 4K.

I have not looked at 1080p in detail.

Hope that helps.

4K ?

Hm... I use full HD (1920x1080) resolution and am not planning to change monitors in the near future.

Is C.F. working in GTA V in the native full HD resolution without upscaling to 2K or 4K ?

Which settings did you use in GTA V ? There are a lot of them in game.

Which CrossFire mode did you use ? I haven't found a preset for GTA V.

OK. I have tested my GPUs in the "Ashes of the Singularity: Escalation" game's benchmark. Seems that CrossFire in DX11 is completely broken. DX12 version of the engine shows a 75% FPS gain using the custom settings (DX12, Fullscreen, 1920x1080, 2 GPUs, MSAA=off, all the settings at high, FX=on, CC=on). The same settings with a single GPU show 44 FPS in a GPU focused benchmark. Changing to 2 GPUs increases the framerate to 77 FPS. FPS Monitor shows that both GPUs are loaded at 99..100% and this is great.

Repost what you said.

I think you were telling me you do not want to use VSR and that other games supposedly work great at 1080p DX11 CrossFire according to YouTube videos.

They may well do.

I only looked at the two games you asked me to.

GTAV and Project Cars 2.

I really do not understand why you would not want to turn on VSR and utilise both GPU at 2K/4K downscaled to your 1080p screen. You may be able to turn off in game AA, and get better image quality and better frame rate on your 1080p monitor.

I think you mentioned "The Witcher" - is that 1 2 3 ?

I can easily take a look at those again.

Also Ashes of the Singularity - which benchmark - Original or Escalation?

There has never been a "Golden Age of AMD DX11 CrossFire FYI".

Games that supposed to support it at launch rarely did, often took lots of effort from people like me to post problems on this forum and even then sometimes it never worked after AMD worked with Game Devs to try.

Mass Effect Andromeda was a perfect example.

Ashes of the Singularity does not use Crossfire. Crossfire isn't a thing in DX12. Using multiple GPU's is the responsibility of the application developer with DX12, which is why it's hardly ever done. Ashes is one of the exceptions, which is why it scales with multiple GPU's.

Crossfire worked in nearly every game before DX11, because there wasn't much of anything a game could do to sabotage it. With DX11 is when it became more troublesome. And with DX12, impossible. That's why it's difficult to get working well today with any modern games. Using much older drivers for older games will probably work OK, but they might not work as well with a single card in modern games.

RE: Framerate in 2K and 4K will be lower than in full HD. That is why I don't want to use VSR.

I have already shown the DX11 games with Crossfire you asked about such as Project cars and GTAV are actually working very well at higher resolution (2k/4k) using VSR on a Pair of R9 Fury X driving a 1080p monitor.

If you run a single GPU with DX11 Crossfire off with a particular AA Setting, you could set VSR to 2K or 4K, get higher quality of image, use both GPU and get good crossfire scaling. You could improve framerate futher by tuning down AA settings that you would use on a single GPU to get the same image quality. That should improve frame rates further. I did not do that in the results I provided.

Just because DX11 Crossfire does not provide benefit on those two games at 1080p DOES NOT MEAN that DX11 Crossfire will not give some additional performance boost on other old games that still support it at 1080p.

DX12 MultiGPU is completely different to DX11 Crossfire.

They are not "Both Crossfire", despite the fact that AMD have a "Crossfire" button that can be used to control DX12 MultiGPU on or off in some games. In others you are told to use the Game interface to control it and make sure to leave the "Crossfire button" off.

As for your Ashes of the Singularity benchmark data - and the subsequent comments about it. I will take a look.

Last time I rememnber testing it, that game supports the following API:

DX11

DX12

Vulkan.

I am going to go look at "The Witcher 3", Crysis 2/3, and Ashes to see how they perform.

RE: If DX11 is so difficult to work with.

That is just not true.

RE: Then I will play only games supporting DX12 and multi GPU feature.
