I ran into something interesting recently, which was if I did this…\r\n```cpp\r\nlong mylong = labs(myfloat * 10000);\r\n```\r\n…the result was different than if I did this…\r\n```cpp\r\nlong mylong = labs(myfloat * 10000.0);\r\n```\r\nSo @toby4548 try this instead. Make the change as above, but use this line as replacement:\r\n```cpp\r\nblock->steps[E_AXIS] = labs(de) * volumetric_multiplier[extruder] * extruder_multiplier[extruder] * 0.1;\r\n```"}}
